This is such a great idea. goes on purple and then dries clear. Keeps you from over doing the glue. Always have fun projects when the grandkids come over. They head straight for the fun.
Caution! The glue when dry does not stick to the Staple brand plain envelope. Some other such as Electric billing envelopes it worked on but I can't take the chance. I found this out after my boss accused me of forgetting to seal his bill. I had to inspect the envelope to be sure I had used the glue to seal the thing in the first place. I threw them all away. I tried the other Staple brand...it did the same thing. I am using tape until I can find a glue stick that I can rely on.
