3rd picture shows the new spool next to an original for comparison (original not included). Pops open and snaps closed just like the original, spins freely on its post, and fits perfectly in original cartridge.

New 3D printed cartridges that also work with these spools will be available soon--designs are still being prototyped. They will be significantly more affordable than other vintage cartridges and current reproduction cartridges.

Listing price is for ONE (1) spool, but you will receive a 30% discount if purchasing a pair.

Ships free.

Thanks for looking!
