Comments about Liquid Flow Dispenser:

These looked to be EXACTLY what I needed to dispense acrylic screen printing ink in my classroom-- previously I'd used squeeze bottles with an opening so small (when the tip was removed) that I'd have to use a funnel to fill them.

Then I read the previous review on the item, and was worried-- but bought them anyway.

SO glad I did. I think the other reviewer didn't realize that the opening on the tip, as it comes, is TINY, barely a pinhole... yes, in that case, when you squeeze it the cap does pop off. BUT-- if you trim the tip and create a larger opening... they're FANTASTIC. I think they're meant to be used this way. Perhaps there should be a caveat in the item description that explains this.

Comments about Liquid Flow Dispenser:

You cannot squeeze this container! So, it's only useful if the liquid you're trying to dispense can flow out via good ol' gravity feed.

I tried to use one of these containers for dispensing acrylic paint, but the paint wouldn't come out, so I tried squeezing the container. Ugh...the lid came off, the paint went everywhere, and my almost-finished artwork was ruined. I wasn't using a very viscous paint, either. I was using watered down Blickcrylic that was about the consistency of thin pancake batter.

This thing is worse than useless.
