They work well and, you get A Lot of them!

Fast shipping and item as described. Just too big for my need.

I teach at a school where the classroom doors open out and have to be locked with a key from the outside. To make it easier for us to secure the doors if there is an active shooter situation, I am using these magnets to prevent the always locked door from closing. If there’s an active shooter, I can pull the magnet from the door and my door is instantly locked and I can stay safely in my room with my students. I have made 100 of them. They work very well. I hope I never need to pull the ribbon, but if I do, this magnet may save lives. Excellent product and well priced.

Good product

perfect for electroculture to cover with bees wax. the hole size seems too large until it's covered, then it's just right for the electric fence wire for ground installation. The longer it's in, it seems, the better the effect is.
