Thank you for viewing! This is an original handmade lightweight Box pouch from Kobo 223. 《We have been selling this as a service item, but due to the rising cost of materials, we will be raising the price. Thank you for your understanding.》 For those who want to walk as lightly as possible during overseas travel, mountain climbing, school, commuting, shopping, etc... I use color-coding when mountain climbing to organize small items such as energy bars and underwear. For those who don't want to be the same as everyone else... Made with DuPont Tyvek, which is used as a building material, so even if it gets a little wet, the contents shouldn't get soaked. (However, the seams and zippers are not waterproofed, so some water may seep through the seams.) (Note) Soft type Tyvek will no longer be sold. Kobo 223 will also only have stock while supplies last. 【Features】 ※ The zipper opens wide, making it easy to take things in and out. ※ A zipper tab has been attached to the zipper, making it easier to open and close. ※ Ultra-lightweight!! It's incredibly light! (approx. 10g) ※ Comes with an original tag! 【Material】Tyvek 【Size】Width approx. 14cm x Height 7cm x Depth 9.5cm (Zipper 20cm) ★ Wrinkles are a characteristic of Tyvek. ★ The word "Tyvek" is printed on the back. ★ Since it is handmade, there may be some slight variations. ★ The color and design of the zipper tab may vary. ★ During mountain climbing, I am often in areas where there is no signal, so I may not be able to be reached for 2-3 days. Thank you for your understanding. Thank you very much for viewing.
