ConvaTec Esteem Synergy - Stomahesive Flexible Skin Barrier with Flange (Pre-cut) uses clear foam adhesive to attach the pouch securely to the skin barrier's "landing zone". The "landing Zone" is in the shape of a square and is slightly larger than the round plastic rings on a standard wafer. This allows for an easier application process and precise alignment is not required. These ostomy supplies offer the versatility of a two-piece system with the low profile, comfort, and flexibility of a one-piece system. ConvaTec's Esteem Synergy barrier with flange provides a secure and reliable alternative to the traditional two-piece setup. Economical ostomy supplies.
