This topic is about using disposable bag liners inside an ostomy pouch. The person is having trouble with the liners falling out and is looking for advice on how to keep them secure.

Here are some helpful insights:

1. The disposable bags in question are actually flushable liners designed to fit inside a regular ostomy pouch. Instead of emptying and rinsing the pouch, you simply remove and flush the liner.

2. A brand called Colo-Majic makes these liners. You can find more information about their products on their website at colomajic.com.

3. There is a demonstration video available that shows how to properly insert and secure the liner so it stays in place. You can watch it here: https://www.youtube.com/watch?v=qIk5xDb0uZo.

4. If you're interested in trying these liners, you can request samples through the Colo-Majic website. However, be aware that one person mentioned they had not yet received their samples.
