A lot more filament for a lot less cost than what I could find in any store in my area

I wouldn't dare to use this filament in my 3D printer due to lower quality, however it's fine to use with a 3d pen.

Works as expected and offers bright colors

They work great in her new 3D pen. She loves all the colors.

I wasn’t sure what to expect from this product but my niece was thrilled to have more options for her 3D pen.
