I'm using the plastic cereal boxes to store my open rolls of filament and I wanted a cleaner look than using the dry erase markers and tags.

I designed the tags to use the common 5/16 x 1/8 magnets found at Harbor Freight. I just glued them into the back of the tags and then I just use a corresponding magnet on the inside of the box.

I printed these in PETG. If there is a particular brand or material that you would like added, leave a comment and I'll update as I receive them.
