Looking for a strong cost effective multi-use premium mini-magnet? Our thin neodymium disc magnet, 7.5x1mm (roughly 5/16x1/16") may be the solution to your problem. These durable craft mini-magnets are plated with nickel coatings for corrosion resistance. Get great value for just a few at $0.30 each or save on quantity. Discounts start at just 10 pieces with further savings at 100+ & 1000+. We have large supplies in stock that usually ship within 1-2 business days.

Indigo magnets are fully documented for guaranteed magnetic flux & a pull force of 0.87lbs (400 grams), see below. Beware of promises of small business empowerment with exaggerated strength claims. A better comparison is with a 1 inch 25mm round ferrite magnet that needs more material than our 7.5x1mm circular Nd disc for small objects like ceramic button fridge magnets.

This is what one customer had to say about Indigo magnets: "I purchased (Indigo's) N42 Neodymium magnets, they are the real deal. I had previously bought magnets on Amazon that were advertised as N52, they were just another cheap Chinese fake. These folks sell authentic, high quality stuff and get it to you fast."

Magnets stuck nicely to my c-clamps and to my stainless steel scissors. The 9 magnet column was strong enough to pull the one separated magnet across 6 inches quicker than a cat can blink an eye! All the people I talked to at Indigo Instruments were helpful and nice, and curbside pickup was seamless.

— Indigo: Thank you for review. Note the safety instructions for magnets. Having them fly towards each other can cause damage and/or injury.

MAG-nificient. Seriously high quality product. They have always been well and smoothly plated (not prone to flaking). Reliable from batch to batch in their consistency of strength and dimensions. I even found them to shatter less often than every other magnet vendor I have found! And a big shout out to their delivery team. You ship fast and reliably every time, everywhere. Keep up the great work.
