I purchased this a few years ago and used it once, but I haven't had a chance to use it since, so I'm selling it. There are faint stains visible in the photos of the 4th, 5th, and 6th images. Please take a look. (The 5th and 6th images show the same stain) New size x new outer material, a Japan-exclusive waxed canvas cooler bag. ● This cooler bag is the first from AO Coolers to use waxed canvas cotton fabric. ● In addition to the durability of the canvas fabric, it is also water-repellent. ● The more you use it, the more it will fit your hand, and the texture and color will change, allowing you to enjoy the aging process. This is the first outer material for AO Coolers. ● The inner material uses a high-quality TPU liner, the same material used in waterbeds and pools that are placed on the ground. ● The internal insulation uses 1.9cm thick, high-density closed-cell foam. ● Due to the combination of materials, it can maintain ice for approximately 24 hours in an outside temperature of 49°C, depending on the size, demonstrating amazing cooling power. ● Comes with a removable and adjustable shoulder strap. The pad portion also uses waxed canvas cotton fabric. ● Uses a YKK zipper. ● A 5-year warranty is provided for products where water leakage due to material/manufacturing defects is recognized. ※ Please note that due to the nature of the product, unevenness in the wax and folding wrinkles may be noticeable.
