Why is there no 1Kg option for Fiberon™?

We've been getting an influx of questions regarding our spool sizing so we hope this helps!

The core of Fiberon™ spools needs to be thicker in order to not have the filament curve at too steep of an angle. CF and GF blends are more likely to snap if bent at too extreme of an angle.

Because the core is larger - 1KG worth of Fiberon™ material will not fit on a 1KG spool.
