Helpful, good size, but not great

These magnets are rather simple, but beautiful, colorful, and the format suits me (about a piece of 5cts level circumference)
However, I do not find them very sturdy, because the magnet lacks power. I expected a "force of attraction" more important, a stronger magnetic power. To snap a photo, it's okay, but the photo can slide over the long term
In short, pretty magnets kindly fulfill their role, but do not expect to be able to magnetize three superimposed sheets
