Yes. Convatec 400598 is a one piece flat, not convex, clear, no vent, clip closure. I wore it for a long time, but now my stoma is retracted and I need a convex wafer. The 400598, 400599 opaque, is soft and very comfortable. You will need OSTO EZ VENTS for venting. It does not turtleneck. When my stoma retracted it would go sideways and force the sewage under the wafer and out.
convatec phone for samples 800 422 8811.
Don't forget the vents......you MUST have them for venting.
