A very good variety of colors
I gave this 5 out of 5 stars
This 3DPrime Twine ABS 3D pen refills pack is perfect for my 3D pen, in fact most 3D pens. It works for all 1.75mm models. There are 12 vacuum sealed rolls in the box and each roll is 20 feet long. There are 12 different colors. This pack is perfect when looking for a variety of color. Included is, purple, blue, green, orange, pink, red, black yellow, gray, white and 2 shades of brown. They colors are bright and will not fade. It melts smoothly and there are not irregular spots or bubbles. They work perfectly in my 3D pen, I just need to get better at using the pen. I received this item at a discounted rate to try in exchange for my honest and unbiased review.
