Since the end of last year, green has been added to the standard colors of the slim coin purse "Undo."

Green was previously a standard color, but was removed from the standard lineup for a while. However, due to many requests from customers, it has been brought back as a new standard color for this production.
In this article, we will introduce the appeal of the Undo coin case and green Buttero.

What is "Undo," a long-selling app that has been around for over 20 years?
Undo is a slim coin case that Munekawa has been making for over 20 years .
It's compact enough to fit in the palm of your hand and can hold around 20-30 coins.

The more you use it, the more the leather will soften and become thinner, down to just 7mm , so it won't ruin your silhouette even if you put it in your inside jacket pocket or pants pocket.It's also light, weighing just 20g , making it easy to carry around, which is one of its popular features.
Tips on how to use it
When opening the Undo wallet, lift the opening slightly with your index finger to prevent coins from spilling out. It takes a little skill to get used to it, but once you get the hang of it, you'll be able to quickly take out coins with one hand.

It also has a small multi-pocket , so you can conveniently store a bill inside. Even if you mainly use cashless payments, this is useful in situations where only cash can be used, such as parking lots and vending machines.
Grows to suit your usage
When you first start using it, the leather is stiff and some people wonder if they can really fit coins in it. However, as you use it, the leather will soften and the amount of coins it can hold will increase.

The same Undo app will be familiar to someone who normally carries around 10 sheets, and someone who carries around 30 sheets. It will grow to suit your usage. That's one of the fun things about Undo.
The charm of Buttero green
Undo is made with Buttero leather from Walpier, an Italian company . This vegetable tanned cowhide leather is a standard feature of Munekawa.

Buttero's distinctive feature is its transparent dyeing process. It is not a thick coating applied to the surface of the leather, but rather a finish that allows the natural look of the leather to be seen.
For this reason, the leather may show unique characteristics unique to natural materials, such as wrinkles and blood vessels, and one of Buttero's special features is that you can enjoy these unique leather features .
Another attractive feature of Buttero is its rich aging. The more you use it, the more glossy it becomes and the deeper the color becomes.
The Buttero leather used by Munekawa is made using an original process that presses the leather fibers under high temperature and pressure.
This not only increases the density and strength of the leather, but also gives the originally matte texture of Buttero a natural luster, adding an elegant and luxurious feel.
Green's revival
Green has been added to the standard color lineup this time.
Previously, it was produced as a standard color, Munekawa is produced by a small number of people, so production is limited and it was removed from the lineup for a while.
However, we received many requests from customers to make green again , so at the end of last year it was brought back as a standard color.

Compared to black, blue, and camel, green has a more subdued impression, but also has just the right amount of individuality. It won't stand out in business settings, and it can also be used as an accent in casual settings.
Green is also a color that ages easily.
When unused, the color is a slightly lighter green, but as you use it, it will deepen and turn into a more subdued shade. For those who enjoy the pleasure of nurturing leather, this color makes it easy to see the change in color.

If you're looking for something different from the usual black, but don't want something too flashy, green might be a good choice.
Pair with a wallet
Recently, more and more people are choosing wallets that only hold cards and bills and do not have a coin purse. This is due to the popularity of cashless payments, which means fewer opportunities to use coins.
The lack of a coin purse makes the wallet slim and compact. Its advantage is that it doesn't take up much space in your pocket and can be carried around smartly.

However, there are still situations where you can only use cash, such as parking lots and vending machines. For those situations, it's a good idea to carry a compact coin case. Separating your wallet and coin case also has the advantage of keeping them both slim.
Enjoy the color combination
Undo's green color has become a standard, expanding the range of color combinations available for wallets and coin cases.

If you use the same green for everything, it will create a unified and calm impression. If you choose different colors, such as a black wallet and a green coin case, you can have fun using them differently.
Every time you open your wallet, you'll see your favorite leather accessories. This small sense of satisfaction will enrich your daily life.

Ideas for long-term use
Munekawa's products are made with the assumption that they will be used for a long time. We would like to introduce some of the ideas and efforts that go into making this possible.
Free replacement of hooks
Since hook and eye buttons are opened and closed every day, deterioration is inevitable over time. Therefore, we will replace your hook and eye buttons free of charge, no matter how many times you have used them.
If you request delivery, you will only be responsible for the round-trip shipping costs. We will return your item to you within one week of receiving it.
No stitching

To prevent the threads from fraying, the current Undo has been improved to a construction without stitching. Coin cases are opened and closed many times every day, so we continue to review the specifications of the details to ensure that the case can withstand that stress.
