Small and inexpensive, you can buy a bunch for a low price. They are great for hanging photos, as one or two of them will hold a picture firmly to a metal surface, and they are virtually invisible. You can also make these little magnets do some strange and interesting things around larger magnets. Using the flat surfaces on solid steel, we were able to get one of these magnets to hold over 7 oz. That is over 2000 times the weight of one magnet! Simply amazing! This size is also available in grade N52 with black nickel plating as part number D21B-N52 and in High Temp grade N42SH as part number D21SH.   D21: 10 for $1.00 25 for $2.50 50 for $5.00 100 for $9.00 250 for $22.50 500 for $40.00 1000 for $80.00 2500 for $175.00 5000 for $350.00 10000 for $600.00 Quantity: « Previous | Next »
