Skilled at 3D printing & want to make wallet size magnetic mini-picture frames? These small 3x1mm Nd disc magnetics have a 110g holding force. Enough for narrow borders & limited cropping for maximum exposure of your favorite family photos. You only need 4 for your DIY magnet photo frames to fit fridges, filing or storage cabinets, dishwashers, dry erase boards or locker accessories.

We have sold NdFeB magnets since 1996 and N42 grade since 2003, the best value for strength & temperature vs cost. Don't be fooled by claims of higher strength, N52, at lower cost.

This is the third time I've ordered these magnets from Indigo Instruments. They are perfect for building miniatures, and they arrived very quickly in the mail (which is in itself remarkable considering the mail volumes right now!). When I use up these magnets, I will definitely be ordering more from here.

I used these magnets for building models, their size and strength are great for small panel sections that need led lighting and access without gluing sections together. Shipping was fast and well packed. Magnets are the perfect size and exactly what I needed, for the price you can't beat it! I highly recommend buying from them! and I will be back for more in the future. Thanks .
