I'm using these and plan to use parafilm to ensure that they stay sealed. They came with a funnel and a white marker for labeling them, which I thought was convenient.

The parafilm is probably overkill, but I figure it can't hurt.

Just got these delivered today. They’re out of stock right now, but maybe heart them or add them to a list and see if they come back around?
