The glue stick is a fine innovation but what the creators didn’t anticipate is the mess that happens when you try to apply glue to the edges of a sheet of paper. I place an old newspaper beneath the sheet to prevent accidental gluing of other stuff. InGlue Stick resolves the issue with a clever redesigning of the cap. A slight cut in the cap and an innovative twist-to-open system, allows you to slide a sheet into the gap. I think it’s a problem-solved design! Hurrah!
