I collect Warhammer 40k miniatures and wanted to use them in bases for easy storage and transport of my models. They were slightly thicker than the 25mm thickness of the base and therefore jutted out. They fit perfectly on all my bases larger than 25mm. With every base size I had the problem that my CA wasn't strong enough to hold the magnet to the base. I use HVAC sheet metal in my tote bag and the magnet sticks to the sheet metal so tightly that the magnet pulls away from the adhesive and therefore my model and stays on the aluminum. I can't deduct stars because it works great. I just need to reconsider my application. I'm thinking about buying a strong glue, maybe a rubber glue. TLDR; If you need a very strong and small magnet, they will fit.
