We recommend you wash your feather clothes with cold water and basic soap powder. Once the washing cycle has been completed, let the clothes dry on a horizontal surface, away from sources of heat and turn them around every so often, taking advantage of the movement of the pen inside. If you are going to use a tumble dryer, we recommend that you use a program with the lowest possible temperature and place 2 or 3 clean tennis balls inside to prevent the boom from clumping. DO NOT iron your garment and never use softener or similar products.
