This magnet includes a 10-year warranty for its magnetic strength, provided it is used under normal conditions.

    Perfect for gaming table accessories

    Posted by Steve on Jun 18th 2025

    I use these for 3D printed accessories for my Wyrmwood gaming table: dice trays, cell phone holders, card holders, etc. They work perfectly. So nice to have the red marks on the sides of the magnet to let me know which end to put in. CMS also ships very quickly and packages them in extra bubble wrap. The magnets come with plastic discs between them to further protect them.
