Good quality. Fibrous material construction with a sealing strip you need to wet to seal. Hold up well to the heat and humidity.

Used these to hold seeded paper as a school giveaway. They are much smaller than a normal seed packet, and they are a one stick use, just like a normal envelope.

They seem well made and durable, just not what i wanted, but no fault of the manufacturer. They are cheap so it's no big deal to replace.

Advertised as self adhesive, but is actually gummed. It isn’t resealable. There is no adhesive on the flap, and the paper is flimsy.
