Although unused, the Tyvek® material has wrinkles and creases due to its nature. The material is highly water-resistant, but please note that it is not completely waterproof. This is a handmade item by an amateur, not a manufactured product. Please refrain from purchasing if you are looking for perfection. ★Tyvek® Silver is a sheet made by vapor-depositing aluminum onto high-density polyethylene non-woven fabric Tyvek®, and then applying an antioxidant resin coating to each individual fiber to prevent aluminum degradation. Unlike other companies' products, which simply sandwich a thin waterproof film with breathable aluminum, this is a robust building material with little degradation in waterproofness even after long-term use.
