I bought these hoping they would fit 1, 2 and 4 oz bottles of ZAP a Gap or Gorilla Glue which they don't do. You are too small. You can easily heat and adjust them with a lighter. but it's a fine line to walk and it kind of defeats the purpose. You have to be more versatile to make it worthwhile. Don't just buy the Zap a Gap brand. Or at least make a cone in your design so they can be adapted to many brands of glue.
