Perfect for tie-dye! Use these for storing and applying liquid dyes. Bottles include your choice of either 1 Yorker spout w/ small conical snap-on cap* or 1 white, flat screw-on cap. *The little yellow snap-on on Yorker Spout tops only come with yorker spouts, and are not available for separate purchase. Due to limited available inventory the color of Yorker snap-on caps may be either red, yellow or clear. Pro Tips: Since these are mechanically mass produced, occasionally some spouts will come in that don't "squirt straight" or leak around the threads. Plumber's tape, that thin white stretchy stuff found at hardware or irrigation supply stores, is a quick easy fix for leaks - a couple of wraps around the threads works like a charm - no tie-dyer should be without it! A simple quick poke with the end of a paper clip will open the tip properly. For less messy dye mixing, paste up your dyes in a separate container. Then, use a funnel to pour into the squeeze bottle and add your water as usual. FYI on Spouts and Caps: The 2/4/8/16 oz. bottles use 24-410 spouts and caps. The 32 oz. bottles use 28-410 spouts and caps. If you find yourself missing some closures, additional screw-on Caps and Yorker Spouts can also be purchased separately!
