I know this would help me, perhaps it would help other customers as well.
I would like you to improve the labels supplied with your refills.
(Actually, your full spools would benefit with suggest #1 below as well)
#1 β They should not only contain the material, but also contain the color of the filament!
#2 β They should take into account whatever color spool is being used for legibility. A clear sticker is not a good idea. Might I suggest black on a white sticker or white on a black sticker.
Thanks so much for taking this into consideration.
