I use these exclusively for all of my tiny and fragile seeds. The seal is tight and they are very resilient to crushing or popping open.

We use these to hold spices when we go backpacking. They hold just enough and they stay closed. I used a dymo-marker to label each tube.

Items are okay but they leak if not standing upright. I thought it would be leak-proof.
