Reasons Why
MPS
If no can unpick lining
Attach magnet catch to piece of leather and glue it on, make it at least 60mm by 60mm
If the magnet catch is weak, wobbly or loose you may have a none matching pair, the bump on the non magnetic side is too long and it hits the bottom of the centre hole of the magnetic side so the flat faces dont get close enough to grip properly
