# Foldable Stitch-Free Wallets The 'Tsutumu' Card Case Comes Flatpacked and Requires Shaping By Michael Hemsworth | Published 2018-02-20 | Fashion Source: Trend Hunter, https://www.trendhunter.com/trends/tsutumu-card-case References: [yankodesign](http://www.yankodesign.com/2018/02/20/this-card-case-is-a-single-leather-piece/) & [syrinx.audio](http://syrinx.audio/products/tsutsumu_card_case.php) The vast majority of wallets on the market are created by utilizing a series of rivets or stitches to keep the accessory together, but the 'Tsutumu' card case takes things in a different direction. Designed by Hirotaka Satoh, the wallet is delivered to the consumer in a [flatpack form](https://www.trendhunter.com/trends/walle-stool) that needs to be folded into the shape required to keep your cards and cash tucked within. This creates a beautifully ornate final aesthetic that won't fall apart with daily use, while the fold lines will begin to patina and garner a rustic look with continued use. The 'Tsutumu' card case has been chromatically designed in a wide array of different colors and speaks to the growing consumer demand for [minimalistic style products](https://www.trendhunter.com/trends/reaf-wallet) as more shoppers shift away from fast fashion options.
