Use this tall magnet for a DIY push pin. Works with wood or polymer clay & can hold up 1 piece of paper or a small stack. Use as a magnet holding push pin on magnetic white boards or any surface that is a magnet friendly metal surface.

We have sold NdFeB magnets since 1996 and have offered N42 grade since 2003, the best value for strength vs cost then & now. Don't be fooled by claims of higher strength, N52, at lower cost:
"...(Indigo) N42 Neodymium magnets...the real deal…bought magnets on Amazon advertised as N52… another cheap Chinese fake". Read the complete review.
