These little boxes have magnets printed into all 4 sides so they will line up nicely and stay together. They come with lids. These can be used to store your diamonds for diamond paintings or other small trinkets. They measure 40 mm x 40 mm x 20 mm (without lid).
These are 3D printed with PLA and are printed in random colours. As with all 3D printing, there may be slight imperfections that do not impact on their intended use.
