These are very nice magnets. I wasn't sure what size and strength I needed for my project so I ordered a small supply of two different ones to test first. Both are great and will work great for what I am creating. I will definitely be ordering more magnets from Indigo Instruments. They were carefully packaged with the other products I ordered and arrived very promptly. The customer service is great.
