The Natura + Two Piece Pouches are compatible with SUR-FIT Natura Two-Piece Ostomy System which is ConvaTec’s most extensive two-piece product line. The SUR-FIT Natura and Natura + Flange System signals a secure, accurate closure with a series of audible “clicks”. The security of the InvisiClose tail closure with Lock-it Pocket ConvaTec’s pouches is combined with SUR-FIT Natura advanced skin barrier adhesives that offer you the security, comfort and discretion you deserve. A simple snap-off, snap on design allows users to change the pouch quickly to match activities without removing the skin barrier from the skin. *Pouch ONLY, barrier sold separately*
