Have you ever had a problem with the nozzle on your glue bottle getting clogged after several uses? You push the sleeve down and wipe the tip yet the next time you need some glue the nozzle is clogged up and you spend more time than necessary making it work. Doesn't matter the brand, they all use the same style nozzle. Sound familiar, well there's a simple fix. Just swap out the cap that come on the glue bottle. Those squeeze bottles of mustard have a flip top cap that fits the top of a glue bottle and doesn't get clogged. The only caution to making this work, is to make sure you hear the "click" when closing the cap so you know you've got it closed tightly
