25 Colors PCL 3D Pen Filament Refill for 3Doodler Start+ 3D Pen, Low Print Temperature Filament Only Fit for 3Doodler Start 3D Pen, Each Color 15cm x 10pc, Total 250pcs 3750cm PCL Filament by MIKA3D

These worked very well with the 3D pen we have. Would definitely reocmmend.

Excellent choice

This stuff was great for the price, I have a cheap 3D printer and it managed this filament like it was nothing. I loved the transition in between colors and the amount per sample. I would suggest doing a test print on your least favorite sample before committing to a full print as the temp and speed settings could be different to other filament brands.

This filament is great for variety. It went through my Flashforge just fine and printed well.

Ideal para lapiz 3d, regala tiempo de diversión fuera de las pantallas, colores variados, buena cantidad, quedamos encantados

Some of the ends have a tiny piece that isn't perfect, but otherwise they are all great. Will absolutely order again once my Daughter uses them all

This set of 3D pen filament refills has a great assortment of colors for creating many different items. They do not clog the pen, and the size fits the pen nicely. Anything you create with these are nice and shiny and sturdy

These worked perfect with my daughter's 3D pen. We had no problems putting it in the pen and making things with them. I would recommend these if you're looking for refills for your 3D pen.

Absolutely terrible does not work properly very disappointed not recommended for you to buy.

Muy buen surtido!

I used the assorted colors in a 3d pen. Unfortunately it wasn't shiny or rainbow for the 3d pen. Maybe better off in a printer.
