This topic is about a new ostomate who recently had surgery and is experiencing issues with the sizing of Coloplast ostomy bags. They prefer the Coloplast 1-piece drainable system in a specific pre-cut size, but have encountered repeated problems with mislabeled products, leading to leaks. They are trying to figure out whether the manufacturer, Coloplast, or the supplier, Edgepark, is responsible for these issues and are seeking advice on how to proceed.

Here are some helpful insights and advice:

1. Mislabeling or size mismatches in ostomy pouches are considered manufacturing defects. It's recommended to contact Coloplast’s replacement or complaint line at 1-855-863-3910 to open a formal case.

2. Suppliers like Edgepark are responsible for handling shipping errors, such as wrong items or damaged goods. However, they generally rely on the manufacturer’s labeling. It's still important to file a complaint with Edgepark so they can escalate the issue.

3. Not all products are affected by this defect. Some users have received correctly labeled deep-convex Coloplast 13/16" boxes from Edgepark, suggesting the problem might be specific to certain batches.

4. A fellow community member has offered spare boxes of Coloplast light-convex 13/16" wafers if they are suitable for the person experiencing the issue.

5. As an alternative, consider using cut-to-fit pouches or wafers with ostomy scissors, which can be helpful if your stoma changes shape or size.

6. Some product alternatives mentioned include:
- Coloplast Sensura Mio Convex, which is available in the U.S.
- Salts Healthcare bags, which are praised but not currently distributed in the U.S.

7. Switching distributors, such as moving from Edgepark to Byram, might help determine if the problem is limited to one distributor’s inventory.
