These liners are the absolute best and save me a lot of money. I hardly buy pouches anymore because now mine don't wear out
I just wash them lightly and wear them again. They never get soiled because the pouches are protected by these liners and the liners are sooo cheap.
When you're away from home, you simply remove the liner, empty it and dispose of it. Then put a new liner in your pouch and you're good to go in just a few minutes.
