Filament is wound around a cardboard core and secured with straps. This allows the reuse of the spool sides, reducing waste.

    Definitely better than the usual full plastic spool, but IMHO a step back from “true” masterspool refills. I’ve already printed my MS spools, switching in a new refill is easy enough, and I never bother to store an already opened refill without a spool since I store all of my filament in a drybox anyway.
