It is simple to transform your favorite wine bottle, liquor bottle, mason jar or vintage bottle into a sink-side piece of art. Great for gifts, home decorating or selling at craft shows. Bathroom uses include soap, lotion, shampoo, conditioner, mouthwash, and hand sanitizer. Kitchen or bar uses include liquor, flavored syrups, dish soap, hand soap, your favorite hot sauce or olive oil. Pumps are handmade in stainless steel with an internal stainless steel spring and glass ball to make them uniquely 100% rust proof. They have been factory tested to be good for over 20,000 pumps. They will pump a full 2 cc of liquid - which is twice the amount of other DIY pumps and will work with even the thickest liquid or lotion. These pumps have an elegant clean look and are our most popular pump. Directions for Use: Pump lids can be screwed directly on to most standard bottles. You can test a bottle to see if it is the right size by screwing on a cap from a 2 liter Pepsi/Coke, Jack Daniels or Jagermeister Bottle. We have provided an extra long 10 inch tube which will fit to the bottom of even the tallest bottles, (up to a 11 1/2 inch tall bottle). For smaller bottles, you can easily cut to length. For use with mason jars: Place the collar ring below the mason jar lid and screw into the pump lid to hold the pump in place. You can punch or drill a hole in the mason jar lid or purchase lids with holes provided for this purpose. For bottles that do not fit or do not have threads, (such as a vintage Coke bottle): The collar ring can be glued on to the top of the bottle. The pump will then screw directly into the collar ring. For gluing to glass, we recommend 3M Scotch-Weld DP8005. You should score the glass with an emery board before gluing.
