I've been buying drams for a while now. Everyone that I've tried are always so difficult to use. The little orifice part is super hard to push in. Fill 10 sample bottles and you know what I mean. But not these drams! The orifice slides right in, and it's super secure! I filled a lot of these up last night and was amazed and how I didn't wear my hand out pushing it down. And the lids are really high quality too. They're almost so nice I don't want to give them away. If you need drams I can't recommend these enough!
