Coloplast Brava - Paste (Sting Free) is a alcohol free skin protecting ostomy paste that works like a caulk to help prevent leaks. This paste-like caulk creates a seal around the stoma and the flange. Brava paste is easy to handle and easy to mold, the flexible nature of the paste allows it to form to your skin. You can use ostomy paste to fill in uneven areas around your stoma to create a flatter surface so your ostomy wafer adheres better. Brava is a skin-friendly paste that resists dissolving and break down. 2 oz tube.
