Hollister Adapt - Flexible Skin Barrier Strip Seals are triangular shaped so that they can be molded and stretched to create custom shapes for maximum fit and conformity. Ostomy paste should be viewed as a caulk and used to fill in uneven areas caused by scars, divots, of skin folds and creases. Ostomy wafers work best when they are placed against even and flat surfaces. These ostomy supplies conform to irregular skin folds and they work well for extended use. Flexible barrier strips can be cut, bent, and stacked together to improve the fit of the ostomy wafer. The over-all length of the ostomy strip paste is 5 1/8”.
