Saves space in your carry-on case, making travel more comfortable. [A-shukurun] compression bags have a two-layer structure of polyethylene and nylon, making them 1.5 times thicker than conventional products, making them less prone to tearing and allowing for repeated use. Strength is improved by 3 to 5 times compared to conventional compression bags! You can use them with confidence even with frequent use. They are the perfect item for many trips, school trips, and business trips. 【3 Times Improved Odor Resistance】 The results of measuring odor leakage after 24 hours by putting ammonia gas into a sealed bag at a domestic inspection institution showed that it was suppressed 13 times more than ordinary bags. Compared to conventional compression bags, the odor resistance is about 3 times higher, so you can prevent unpleasant odors from filling your carry-on case, giving you peace of mind. 【Improved Slider Zipper】 The slider zipper is essential for vacuum compression. [A-shukurun] does not compromise on the slider zipper! Unlike the thin and cheap sliders often found in inexpensive compression bags, we have focused on a slider shape that fits comfortably in the hand, is sturdy, and easy to seal with little force. Furthermore, the zipper that closes the bag is a double zipper, allowing for high sealing performance and easy and reliable connection for anyone. 【Passed Harmful Substance Formaldehyde Test】 The product has been tested by a domestic inspection institution and has cleared the standard value. This allows you to use it with confidence even on delicate skin or with small children. 【Manufactured at a Proven, Excellent Factory】 We were able to contract with one carefully selected factory from over 10 factories specializing in bag production.
