Review: Very good quality magnets - Very good quality magnets. I use mine with a self-adhesive magnetic foil to attach a piece of a paper or cardstock and keep it in place. They are very small, therefore thay can be removed easily.
Review: Incredibly weak - Really weak. Bought them to magnetize and transport some miniatures that are a few grams a piece and it take around 5 magnets to get them even remotely sturdy.
