30 minute set up and your ready to perform. Very easy to do. I love the fact its not an app. Packs small packs big in someone else's pocket. Excellent. Delivered inside two hours of ordering, thanks Monster Magic.
I was using an alternative brand repositionable glue for the flaps on my himber envelopes but it wasn't very good at all. I could never rely on it to hold the flap closed on the underside of the envelope. This glue is awesome. So far I have not had any issue and the flaps have been held in place until I open them
