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.

Good

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

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

It was great being able to get a larger assortment of color options at a more affordable price. My main issue is that these all are coated with some white chalky powder that the name brand doesn’t have. It doesn’t impact printing, but it is annoying to deal with and feel.
