REAL filament (a dutch brand) often comes on a cardboard spool. That's fine, but most filament spool holders may damage and therefore weaken the spool. This ring fits (very snugly!) in the spool, making it sturdy and wear-proof.
Removing this ring will most likely damage the spool, so, print a few sets, recycle them when a spool is empty.
EDIT: Important update, about 3 years late;
Apparently newer REAL spools have a larger hole diameter, 56.5mm as opposed to 56.0mm,
So for newer spools, see images how to identify, scale up by 0.9% (or simply 1% and jam it in there real good ;) )
