We have 1000's of Round Base magnets available in two sizes: 65 lb pull and 25 lb pull.
These same magnets are also listed by diameter: the 65 lb. are 2-5/8 in. (or 6.7 cm.) diameter and the 25 lb. are 2-1/8 in. (or 5.4 cm.) diameter.
The most popular quantities are lots of 2 or 4 magnets in either size, but if you want the lowest cost per item then you need to purchase larger quantities as we will discount shipping on bulk orders. Please contact us if your desired quantity is not listed and we will create a listing for you.
