Use these kraft concentrate envelopes to pack and hold .5 grams -1 gram of shatter or pressed rosin. Our coin envelopes are made of 1m thick durable paper (feels like you're holding 2 thick business cards together), they are extra-deep and have a fully gummed lip so you can seal in the contents. 

Note: We recommend pre-packaging your concentrate in wax or silicone treated parchment paper.
