3D Pen Filament Refills 1.75mm PLA 40 Colors Total 800 Feet (23 Solid / 5 Metallic / 4 Fluo / 4 Transparent / 2 Silk / 2 Glow)- Mega Gift Set with Individual Packs

As a hobbyist, I do quite a bit of printing. I must say I am totally satisfied. Tons of nice , vibrant colors and all are air sealed and labeled. You don`t need to guess. Very nice organization and packaging. Consistently smooth throughout. Produced a couple of small, fine quality prints, and my favorite is the little elephant . The filament flawed nicely around 210 °C in my mini 3D printer at a speed of 20 mm/s with a layer height of 0.12mm. No bubbles, lumps or bad smell. Had a nice smooth finish. It also worked fine in my kids` 3d pens that take 1.75mm PLA. The stencils eBook you get in the follow-up email was a nice addition to the overall experience. It`s great for the kids. All in all, I`d highly recommend.

It does not work very well with 3d printers

I bought 2 boxes for my kids. They both loved them, so did my wife and I. The packaging deserves a credit. It is colorful and stylish. Each of the 40 colors is put in a separate vacuum sealed bag with silica gel and 2 cord ties holding them together. Each pack is marked with color, type, and size of the filament. Really impressive. The colors are vibrant and stay true when printed. Filaments work perfectly with my kids` pens. Nice flow, no jams at all. Feeds into the pen without any issues. Very satisfied so far. Kids already printed a cute guitar. I will definitely be purchasing more from them again.

Muy buen producto de calidad y llego antes de lo esperado, tal y como viene descrito

I thought this would be perfect for my 3doodler pen but no. waste of money. and I had a really cool idea for this. this is just too thin for my pen. I will be refunding or getting a different pen that suits it so it doesn't go to waste

This had an enormous amount of 3D filament. Wide variety of colors including metallics. Kids had fun. Each colored required an adult opening the package. It took some work to remove the outer package and then cut the tiny zip ties that secure each coil of filament.

Good quality and easy to use. I haven't had any issues, and I've been using this for months. It melts, and glides out of the pen easily. Cools instantly as it should and it stays vibrant. No scorching, discoloration or fading.

Perfect solution to needing multiple colors. I used this to begin printing the periodic table of elements with my 3D printer. Worked out perfect. No clogs, no issues.
