I was a little disappointed when I saw these. The quality is fair not good. They are cut kind of crooked. But they still hold small objects and seal fine.
When I travel this size envelope is perfect for keeping a daily portion of pills that i will need. No need for bulky pill boxes. I date each envelope with the date I need to take them. After taking the pills for the day I can discard the envelope and lighten the load in the suitcase.
