Online kindergarten means your kid will play around with glue a lot at home. Being small kids with developing dexterity will inevitably means a lot of mess using regular glue with sponge tip.
The stick glue type wouldn't cut it either. The adhesion power is too low, the stick easily breaks and small kids will generally forgets to close it. Not to mention it's also expensive
As such, the glue with roller tip solves the problem. It will only dispense glue when pressed and it can move smoothly on paper. The adhesion power is as strong as regular glue and you don't need to worry about it caking up if your kid forgets to close it.
