Review on Convenient Plastic Squeeze Bottles with Stainless Applicators for Precision Application by Adam Bates

good deal on 4 different sized applicators and they are actually sealed so they don't leak. I use them to accurately apply coolant when milling and finishing small metal parts with deep grooves that regular 1/4" nozzles on 8 oz or 16 oz coolant bottles can't reach. Too bad I didn't find them much sooner because I used wire for 3 months to dip it in coolant and put 1 drop each on the recesses in the parts I was working on so I'm pretty sure you can imagine how long it took lol!
