I use them for dispensing resin/hardener and 90% alcohol.

Great for dispensing laminating resin/hardener!

Update: I did not even contact Aircraft Spruce, just put a review in for the 2 cut bottles, they are sending new bottles without even contacting me. This has been and is the quality I have always like about aircraft spruce. Rate if changed to a 5 for their great quality control in this subject. Thanks Aircraft Spruce.
