Thin little 1/4" magnets. Very strong and very handy. Like most of the smaller magnets we sell, these are fascinating, reasonably easy to handle and aren't dangerous to fingers. Great multi-purpose size.
This size is also available in grade N52 as part number D41-N52, in grade N52 with a Gold finish as part number D41G-N52 and in High Temp grade N42SH as part number D41SH.
