You can leave the cap off while crafting without problems. Though not recommended, I have to admit I have left mine off for days and the glue is fine.
• A little glue-dot “goober” plug may form in/on the tip of the spout which essentially “caps” the glue. If this happens. it’s usually easy to unplug. First try to pull it out with your fingernails rather than poking it back in with a pin. (You may find dipping a pin into the Best Cleaner Ever™ is helpful to clear a bad plug.)
• The glue may thicken slightly over time. Although many prefer it like this, if you want it thinner, simply add a couple drops of water to thin the glue, but only add a couple drops at a time!
