I am part of a parents' asso. We ordered 2 lots (who arrived well before the date indicated) for creative activity based recycling craft (bottles, caps, cans, wood, chestnuts, acorns, branches, etc) and each child had to create what he wanted. The glue has held. Everyone was delighted, especially we asso, considering the price ... We had no worries in size (we had 3 different pistols, mine is a dremel, the others apparently were first purchased in price FOIRFOUILLE or others).
