I've filled these small envelopes with dried basil flowers and given them out to neighbors. The envelopes are gently crushed and the tiny black seeds that fall into the bottom (about 50 per envelope) are ready to be planted.
We uae these to send out metal dash plaques for car shows. They are strong enough that the metal doesn't tear the paper. Even thoufgh we round the corners of the little plaques some others we had tried still tore.
