The product consists of two adhesive stickers: one large, orange Valve Deactivator, and one small informational label. This is an optional adhesive valve cover and informational sticker advising others that the valve has been sealed and deactivated. Enclosed are 2 stickers to deactivate our masks valve. The larger adhesive seal will deactivate the valve to prevent any chance of droplets being expelled. The smaller sticker shows to onlookers that the valve is deactivated.
