SceneryWorkshop has some new rare-earth magnets available to help you customize your models.
From the update:
SceneryWorkshop is proud to present Rare Earth Magnets in 2mm and 5mm diameter, which makes them perfect to magnetize your mini’s. Drill small holes in the joints of your mini for example, superglue these magnets, and it has never been easier to change weapons and shields on your mini’s, or to convert your Necron Doomsday Ark into a Ghost Ark. They are now available to our Dutch and Belgian customers.
