Under the abdomen, the pouch is often attached without being seen. The Assura flange's mechanical coupling emits an audible click, confirming that the pouch is securely attached. Its convex shape applies gentle pressure around the stoma to maintain contact when the skin has a hollow or a fold.

• The spiral adhesive distributes adhesion around the stoma and keeps the flange firmly in place on the skin
• The opening can be cut to the exact shape of the stoma, useful when it is not perfectly round
• The pouch detaches and is replaced by the mechanical coupling, without touching the flange attached to the skin
