The fast delivery was great! Still have to hold you, these clamps are real toys. Even a baby could come up with this tool, not attach the slightest pain. The Force does not even held 2 balsa wood together. l took 3 clothespins that then the work of 6 of these clamps took over. Actually, one would have to return these goods. Mir is only 1h I need almost every time to deliver a package at the post office, not worth the effort. ---> CONCLUSION: This product is completely useless !!!
