Top magnets, but my fingernails hurt ...

Find these super magnets!
My idea for this was to attach images to a magnetic board firmly as possible without me half of it would have to pick up again every day.
The purpose of meeting these mini magnets super!
The only drawback for me is the magnetic strength ... because the "plates" are so small and really adhere firmly, I get it only from back when I "under Attack" and take off with a fingernail.
After 50 times, it does so slowly to the nail hurt .... but otherwise I can recommend these magnets highly - especially for people with strong nails!
