640ft 3D Pen Filament Refills 40 Colors, 1.75 mm Filament, Compatible with SCRIB3D P1/ADV, MYNT3D Basic/Super/Pro, 3Doodler Flow/Pro, Comes with 2 Finger Caps & Stencil

My son loves this. We also like that it comes with the finger guards. The colors and variety are great! There is plenty of each color for a multitude of projects. The quality of the filament is great and his projects turn out durable. We are still learning how different temperatures effect the filament and print speed but everything seems to work as one would hope.

Lots of colors. My kid loves to use her 3D pen. These refills work great. Have had no issues.

Great product and amazing price. Will purchase this again for my son to use in his 3d Printer Pen.

Better than I expected. I bought this as an experiment for my new 3D printer (Bambu Lab A1 Mini). You get about 12g of each color, but the amounts aren't very precisely measured. I was disappointed by the packaging. The filament arrives in a simple box without any sealed plastic bag, so the filament is potentially soggy. As I feared, my small prints yielded mixed results. Some colors printed perfectly while others were stringy. But I was happy my printer detected and of filament and let me load another color mid-print, resulting in some interesting rainbow prints. Just be sure to dry your filament before use.

Great colors perfect for 3D pen

Seems to work well in the Scrib3d unit. Seems to work best on its PLA setting once it gets to operating temperature. Will probably buy more when needed.

My kids love them

Make sure you get the right size for the right pen. I’ve never bought these before. I had the wrong size the first time second time I got it right but I wish I’d been more educated on how this stuff works, but that’s my problem. I’m learning, but it’s everything that says grandson loves it.

Las compré para un pluma 3d y eran demasiado duras. No se podian trabajar.
