This topic is about the sudden unavailability of ConvaTec Sur-Fit Natura Disposable Convex Inserts, which many people have relied on for years. Recently, these inserts have been hard to find, with suppliers reporting back-orders, and the only available option being much more expensive on Amazon. This has led to frequent appliance changes due to leaks. Here are some insights and advice shared by others facing the same issue:

1. The shortage is due to a temporary supply interruption, not a discontinuation. A ConvaTec manufacturing plant was affected by a hurricane, causing delays.

2. Consider trying substitutes while waiting for the original inserts to become available:
- Hollister Adapt Convexity Inserts, which stick to the flange. You can request samples online.
- Other Hollister convex products or Coloplast convex systems. Some users have switched to Coloplast and are satisfied with the change.

3. If your preferred ConvaTec pouches are out of stock, try alternate pouch numbers:
- Original: Natura Drainable Pouch with InvisiClose Outlet #413312.
- Substitute: #416418, though some users report side leakage with this model.

4. To manage leakage with substitute pouches:
- Ensure the leak isn't due to how the single InvisiClose is closed.
- For small leaks, use a Skin-Prep pad to create a temporary seal, or apply a small Duoderm-type patch for a day's protection.
- If an entire box has seam leaks, request a replacement or refund.
- Use panty liners for temporary protection. Tape or adhesive strips might help but could affect the outlet closure.

5. Community support is available. One member has offered free 20 mm Hollister convex inserts for those whose stoma size fits.
