Victorstar@3D Pen Filament 12 Colors+2 Colors Glow in Dark for 3D Printing Pen / 3D Drawing Pen / Diameter 1.75mm ABS-10 Meters (32.8ft) Each Color

I love that these have two glow in the dark colors. It is White that glows green, And blue that glows blue. The colors that come in this set are Red, Pink, Orange, Lime green, dark green, blue, purple, brown, black, grey, and silver. They are easy to insert into the pen. They are easy to melt. Easy to cut once you are done. I have really enjoyed playing with these colors with my pen.
I got these deeply discounted or for free in exchange for my honest review.
