OstoFresh - Hydrocolloid Skin Barrier Ring Seals are skin-friendly tape alternatives that protect and even out skin surfaces next to and around the stoma, fistula, or draining wound. Perfect Choice Hydrocolloid Skin Barrier rings conform to affected areas by stretching and molding around the stoma or wound. OstoFresh are ideal for those with tape allergies and/or sensitive skin. The ostomy barrier rings can be used in and out of water so they don't need to be removed prior to showering. The outer diameter of the barrier ring measures 1 7/8" with a 3/4" inner pre-cut circle. The seal is 2mm thick and is sold in a resealable jar of 10 rings. This product was formerly known as Perfect Choice Hydrocolloid Skin Barrier Ring Seals.
