Agricultural Polyethylene Film, Thickness 0.05mm, 135 x 210, 131g More waterproof, lightweight, and compact than Tyvek sheet. Please refer to photos 2 and 3 for size reference. It's a Cinderella fit with Ziploc M. (Photos 4 and 5 are for illustrative purposes.) It's an item with a good balance of waterproofness, lightness, and durability, and can be used actively. With a thickness of 0.05mm, it's durable and can be used repeatedly, making it excellent value for money. You can play without worrying about dirt. In terms of size, it's a perfect fit for a 2-person tent. When using it in a solo tent, fold it to increase the thickness, or cut it to your preferred size. If you cut it to 90cm wide, it will be about 80g. Since it's a amateur cut, the cut edges are as they are. Fine dust adheres due to static electricity, but it's new. Please be understanding. I will cut it a little longer. 0.03mm is also available. For toughness: 0.05mm For smallness and lightness: 0.03mm Please consider according to your intended use.
