Introducing the IQOS Irma One case! What designs are popular on Rakuten?

2026-10-1 price revision: list by brand and annual cost difference

Lately, I have been using the light and compact Irma One at work and Irma at home.

When I started using Irma One, I thought it was too big and plain to slip and drop.

It would be a big deal for me as a smoker if I dropped it at work and caused it to malfunction.

Today we will introduce a case that can be used with the IQOS Irma One that will dispel these concerns.

IQOS Irma One case

In this article, we will start with Rakuten, which you are likely to use frequently.

Most cases that can be used with the IQOS Irma One are basically sleeves, but Rakuten also has a type of case that can store tobacco sticks at the same time.

We will introduce some of the most popular ones, so if you have been looking for a case, please take a look until the end.

List of materials for the cases introduced today

• genuine
• leather-based
• denim jeans
• silicon-based
• Plastic
• Handmade

genuine

IQOS Irma One Silicone Sleeve

price	980 yen
color	6 types chartreuse citron yellow new indigo (dye) claret red bright coral tinted teal
Supported models	Irma Wang
raw materials	silicon

The genuine silicone cases come in six variations and are available at a low price of 980 yen.

The shape has diagonal lines, so it fits easily in the hand and prevents slipping.

Compared to the Icos 3 Multi, which was also an all-in-one model, the Irma One had the disadvantage of being large and difficult to grip.

However, this cover allows for a firm grip and helps prevent dropping.

There are many colors to choose from, so you will be able to find a cover to your liking.

IQOS Irma One Fabric Sleeve +

price	1,780 yen
color	3 types dark green khaki dark gray
Supported models	Irma Wang
raw materials	fabric

The IQOS Irma One Fabric Sleeve+ comes in a soothing color, unlike the IQOS Irma One Silicone Sleeve.

The fabric material and calm colors of the cover are casual and awesome stylish.

The strap is also a nice feature, so there is no need to worry about losing it or dropping it.

The fabric material is non-slip and helps prevent falling.

Rakuten Leather Systems

Digimoku leather case

Digital Mosaic

price	1,480 yen
color	4 types black navy red carol
Supported models	Irma Wang
raw materials	PU leather

Digimoku leather cases are made of PU leather, which is flexible and resilient, reducing damage even if the case is accidentally dropped.

It has a simple look and feel, yet the leather gives it a luxurious feel.

And what's more, I like that it comes with a strap.

It can be hooked on a bag, hung from the neck, or used in many other ways to prevent loss or falling.

MorioKoubou leather case

Leather bags and wallets MorioKoubou

price	2,388 yen
color	8 types natural yellow camel caramel brown chocolate brown real black navy blue hunter green cherry red
Supported models	Irma Wang
raw materials	oxhide

MorioKoubou's leather cases are made of natural leather from Himeji cowskin, so the more you use them, the more they become familiar with you and you can enjoy the changes they undergo over time.

The simple design matches the high quality leather and looks really cool.

It is also nice to be able to choose the one that fits your carrying style, as there are two types sold, one with a key ring and the other slim type without a key ring.

In addition, you can get "TABANERU-KUN," which organizes the wiring, if you write a review after purchasing the product.

Rakuten Denimkei

Nairn Deco Denim Case

price	1,980 yen
color	2 types blue (colour, color) light blue
Supported models	Irma Wang
raw materials	denim

Most IQOS Irma One cases are sleeve-type cases, but the Nairn Deco case has enough room for a cigarette stick, the device itself, and a portable ashtray.

Incidentally, it comes with a portable ashtray and a carabiner for easy carrying.

It comes in two colors, but they are blue and light blue, which go well with denim, so they are nice and casual and stylish.

Denim Case by Yamanei Shokai Co.

San-ei Shokai Co.

price	3,180 yen
color	5 types navy blue (colour, color) gray (SI unit of absorbed dose of radiation) dark blue light blue
Supported models	Irma One/ICOS 3 Multi
raw materials	denim

The denim case from Yamakae Shokai Co., Ltd. is a stylish looking case and my favorite type.

From the outside, it's hard to believe that there's an IQOS inside this thing, which is good.

Furthermore, it can hold cards in addition to tobacco sticks, so if you are a person who does not usually use cash, you can go out with just a Yamanei Shokai denim case.

The use of PU leather in one spot on the inside is also cool and nice.

Rakuten Silicon System

Pullplastic silicone case

pull plate

price	1,298 yen
color	5 types red blue (colour, color) green pink black
Supported models	Irma Wang
raw materials	silicon

The Pulpra case is made of silicone material, so it fits snugly to the device and protects the Irma One well.

The silicone material is non-slip, so there is no need to worry about slipping and dropping it.

The product is available in vivid colors, so it is perfect for people who like bright colors, and the simple design is cool, too.

TOYSMARKET silicone case

TOYSMARKET

price	1,000 yen
color	9 types navy blue rose engine turquoise green black beige mint lavender light pink
Supported models	Irma Wang
raw materials	silicon

TOYSMARKET's silicone cases come in nine different colors, so you can choose the color you prefer.

It is a simple cover but has a diagonal line on the body, which is a cool accent.

The silicone is non-slip, so there is no need to worry about the case shifting.

Rakuten Plastics, Inc.

SkyMaple plastic case

SkyMaple

price	1,683 yen
color	7 types rose pink purple red green gold blue (colour, color) gun
Supported models	Irma Wang
raw materials	PC

SkyMaple's plastic case is made of plated PC material, so it doesn't look like plastic.

The plating process gives it a glossy sheen, creating a luxurious and stylish look that is very cool.

This is my personal favorite case among the cases presented here.

However, it is plated, so fingerprints may be a negative point.

Gentle Breeze plastic case

gentle breeze

price	1,780 yen
color	1 type red
Supported models	Irma Wang
raw materials	PC +PU

There is only one type of plastic case for Gentle Breeze, but isn't this checkered pattern really cool?

I was excited when I found this case because I have an image that there are not many cases with checkered designs.

I recommend the Gentle Breeze case, which is a bit rarer, to anyone who wants to stand out from the crowd.

Handmade

Handmade case by IZUMITH'S GALLERY

IZUMITH'S GALLERY

price	5,800 yen
color	1 type cardinal red
Supported models	Irma Wang
raw materials	oxhide

The more you use IZUMITH'S GALLERY's handmade cases, the more the leather fibers will loosen and become supple, making them easier to use and giving them a cowhide flavor.

All hardware is made of brass, and the gibbons are also a point of reference for the piece. The gibbons can be replaced with brass spring hook buttons if desired.

I recommend it to women because of its storage capacity, which can also hold cigarette sticks, and the leather color is very pretty.

Handmade case by ROAD810'S GALLERY

ROAD810'S GALLERY

price	5,000 yen
color	1 type brown
Supported models	Irma Wang
raw materials	oxhide

Isn't the case of ROAD810'S GALLERY very austere and cool?

The front and back are two-tone, but the austere design gives the two-tone color a mature look.

For 500 yen, you can also have your name printed on it, and the company also offers good coverage for maintenance and other services.
