3D Pen Filament: 1.75mm, Safe for Kids, Great Quality, High-Precision, Odorless, Compatible with all 3D Pens, 3D Pens/3D Printers, Refill Pack of 15 Vibrant Colors, 10 Feet Each, 70 FREE Stencils

I bought 3x 3D printer pens and blew through the sample filament in less than 1 weekend. My youngest daughter went to work on all three packs. I decided to get a multipack set. We open the packs this morning and ALL of the filament bundles were in pieces. Looking at the imagery I had assumed that it came on rolls. It did not. I was wound and tied with bread ties. This is not a problem in itself. The real issue is that the filament is brittle and breaks easily. 5 minutes into use two of our pens jammed. I had to disassemble the pen and find the guiding filament feed line and the brittle filament had broken into 5 pieces and would not feed through the extruder. A total fail. I will absolutely avoid this brand at all costs. Purchased 3 useless shattered bundles.

Be mindful that the first picture is not accurate. These do not arrive on spools. They arrive coiled with a twist tie holding them together and encased in vacuum sealed plastic. Also I'm not sure where the stencils were supposed to be - they were not in with the filament. I'll have to go retrieve the packaging to see if they are stuffed in the bottom somewhere. We haven't attempted to use them yet, so I can't comment on quality but the colors are nice.

Lots of pretty colors to choose from! I love these! I've made so many little crafts with them. Highly recommend!

My son has been able to make all sorts of crazy things with this filament. He made chicken legs that go on his fingers!

Great variety pack! Packaged together really nicely!

Unfortunately we received at least half of all the colors were broken ☹️ Will not buy this brand again.

mostly little pieces of ink filaments

when this arrived many of the filament pieces were broken apart from S&H I am sure it will still work out in the pen. happy to have more color choices
