Natura + Closed End Pouch with Filter, Opaque, Standard, 57mm, 2 1/4" (Box of 30)

These are very good pouches for your colostomy system. The only problem I have with them is the carbon fiber filter. If you have liquidy stool or there's a lot of mucus coming off your stoma the filter can get wet and sometimes leaks with like a black liquid out of the filter. I found it's easy to stop this if you put one of the filter stickers on and cover it with a piece of tape. That ensures that your shirt and clothing doesn't get messed up and stained.
