【Amazing Compression Bags That Reduce Luggage Volume by 1/4】 With [Ashiukurun] compression bags, bulky items like knitwear and jackets can be compressed to 1/2 to 1/4 their size! This saves space in your carry-on, making travel more comfortable. [Ashiukurun] compression bags use a two-layer structure of polyethylene and nylon, making them 1.5 times thicker than conventional products and less prone to tearing, allowing for repeated use. They achieve 3 to 5 times the strength of conventional compression bags! You can use them with confidence, even with frequent use. They are the perfect item for numerous trips, school trips, and business trips. 【3x Improved Odor Resistance】 [Ashiukurun] was tested by a domestic inspection organization, where ammonia gas was placed in a sealed bag, and the odor leakage after 24 hours was measured. The results showed that the odor was suppressed 13 times more than with general bags. Compared to conventional compression bags, the odor resistance is about 3 times better, preventing unpleasant odors from filling your carry-on, giving you peace of mind. 【Improved Slider Zipper】 The slider zipper is essential for vacuum compression. [Ashiukurun] doesn't compromise on the slider zipper either! Unlike the thin and cheap sliders often found in inexpensive compression bags, we've focused on a sturdy slider shape that fits comfortably in your hand and seals easily with minimal force. Furthermore, the bag closure zipper is a double zipper, providing high sealing performance and allowing anyone to easily and securely connect it. 【Passed Formaldehyde Inspection】 Formaldehyde is full of dangers! Formaldehyde irritates the mucous membranes, causing eye irritation, tearing, runny nose, and inflammation, and is considered a harmful substance that can cause allergic reactions. [Ashiukurun] has been tested by a domestic inspection organization and has cleared the standard values. This allows even delicate skin and young children to use it with peace of mind. 【Manufactured in a Proven, Excellent Factory】 [Ashiukurun] was able to contract with one carefully selected factory from over 10 factories specializing in bag production. The contracted factory has obtained ISO14001 certification and has a track record of shipping 20 million units annually. 【Size/Material】 M size: 32cm x 39cm L size: 35cm x 50cm [Bag] Polyethylene/Nylon [Slider] Polypropylene/ [Slider Zipper] Polyethylene
