Why choose 3.5KG jumbo rolls?

A 3.5KG spool holds 3.5 times the filament of a standard 1KG roll, which is ideal for large prints, production runs and anyone who prints frequently.

Fewer spool changes and less leftover filament mean less waste and fewer interruptions, so your printer keeps running longer between swaps.
