This saves space in your carry-on case, making travel more comfortable. The compression bags have a two-layer structure of polyethylene and nylon, making them 1.5 times thicker than conventional products, and thus less prone to tearing, allowing for repeated use. They are 3 to 5 times stronger than 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. 【3x Improved Odor Resistance】 A domestic inspection agency measured the odor leakage after 24 hours by putting ammonia gas into a sealed bag, and the result showed that it was suppressed 13 times more than ordinary bags. Compared to conventional compression bags, the odor resistance is about 3 times higher, preventing unpleasant odors from filling your carry-on case, so those who are concerned can rest assured. 【Improved Slider Zipper】 The slider zipper is essential for vacuum compression. We don't compromise on the slider zipper either! Unlike the thin and cheap sliders often found in inexpensive compression bags, we have focused on a sturdy slider shape that fits in your hand and is easy to seal even with a small amount of force. Furthermore, the zipper that closes the bag is a double zipper, making it highly airtight and allowing anyone to easily and securely connect it. 【Passed Formaldehyde Inspection for Harmful Substances】 Formaldehyde is full of dangers! Formaldehyde irritates human mucous membranes and is a harmful substance that is considered to be the cause of allergic reactions such as eye irritation, tearing, runny nose, and inflammation. We have passed the standards set by a domestic inspection agency. This allows even delicate skin and small children to use it with peace of mind. $$1000
