Incredibly strong perfect N52 Magnets!

Originally the items i ordered said they would be delivered 11/21. As soon as i placed the order the date changes to the 26th. I was super bummers and reached out to findmag. They were very quick to respond as far as a business goes (maybe 2-3 hours) and advised about Walmart being the place fulfilling the order and they unfortunately cannot make any changes. So i received the magnets today, a day earlier than anticipated and they are in pristine condition. The hopping boxes were a bit beat up but that's to be expected when shipping super strong magnets. They were packed with foam and the magnets themselves did not have a single scratch. The company even sent me a free pair of magnets I'm thinking for the trouble and misunderstanding. Which was extremely AWESOME of them considering they absolutely did not have to. So yes I would definitely recommend just make sure Walmart is correct with their shipping info. Aside from that findmag has a new repeat customer and will be ordering some bigger ones here soon! Purchased the round 40x20mm and square 40x40x20
