You can magnetize Really Useful Boxes with this kit.
This kit is designed for the standard Really Useful Box size that is roughly the size of a piece of paper (8-1/2 x 12").
This kit contains 1 sheet with adhesive that will convert 1 Really Useful Box container into a Ferro-Magnetic carrying case. Ferro-Magnetic means that magnets are attracted to this metal NOT that it is magnetic.

Compatibility with international Really Useful Boxes is not guaranteed as it appears there may be a 2mm difference in the flat surface space on the bottom of the boxes.

Using these Really Useful Box liners are INCREDIBLY easy.
Peal the adhesive paper off of the strips and press firmly to the container.

Make & Care
Our 3D-printed parts are crafted using high-definition resin at a 25-micron layer height, ensuring exceptional detail and quality far beyond standard resin prints.
To provide maximum protection during shipping, your parts will arrive with supports still attached. But don't worry—removing them is a straightforward process!
Simply apply gentle pressure to easily remove the supports without damaging the parts. We recommend starting with a non-essential area to get comfortable with the process.
Once the supports are removed, you may notice some minor remnants that can be easily smoothed out with additional finishing before priming, especially on smaller or more delicate parts. With a little care and patience, your models will be ready for painting and assembly in no time!
It is recommended to wear appropriate protective equipment when sanding resin. Unless otherwise specified, these items will require assembly, either as their own model or as an upgrade for an existing kit. For best results, gel superglue is recommended.
