I would have preferred to give a good rating, but I don't take to not getting what I paid for. My box only had 23 colors. I counts 3 times to be sure. This was a gift for my niece coming out of town for christmas. Her mother is terminally ill and I thoughy this would help keep her mind on hopeful things during her moms transition. She's way to sharp to notice one missing. I'll have to send it back.

I bought this as a gift for my son to use with his 3D pen. The price and color assortment were good for gifting.

Works well with my daughters 3D pen. Very pleased with the colors and the quality.

Great Value

I have two 3D pens, I need filament refills for both of them. And this refill is compatible with my pens. Besides, it is not pricy.
