These are handmade, not manufactured, so please refrain from purchasing if you are looking for perfection. Please understand that the items will be folded for shipping. ★Tyvek® Silver is a sheet made by vapor-depositing aluminum on high-density polyethylene non-woven fabric Tyvek®, and further coating each fiber with an anti-oxidation resin to prevent aluminum degradation. Unlike other products that simply sandwich a breathable aluminum layer between thin waterproof films, this is a robust building material that maintains its waterproof performance for a long time.
