“I've been buying these magnets and their South counterpart for some time now and can fault neither the magnet, nor the service I receive, including speed of delivery. I'm a wedding stationer and these are perfect for holding the flaps on Pocket-fold wallets They have enough strength to feel strong without being difficult to separate and adhesion is excellent. But I do advise that once on they should be allowed a curing time. I leave them 24 hours before delivering, but a couple of hours would be fine. Never had any come off! Definitely recommend for all craft purposes”
