Edit: Seller is phenomenal. Able to contact me and update product listing to ensure it is sold as 3D Pen filament. Even though the product didn’t work for me, the seller was quick in shipping, and attempting to resolve the issues I had. Updated stars, but will show the original review, as this product is best for pens and not printers. Original: After I first got my 3D printer and I’d gone through the included filament, I decided to buy this as my first pack of filament so I could test different colors. The colors themselves are nice… That’s about all the good I have to say about these. I tried several different filaments when I got this package, and I had some issue each time. I thought it was because I was new at 3D printing at first, but when I bought a different spool of filament, I realized I wasn’t doing anything wrong; it was this filament itself. For starters, some colors were very dry right out of the package, and broke every time I tried to load it. Even when I got them fed through correctly, they kept snapping during the printing process, leaving me with a half-completed print. Trying to unload or change filaments also ended badly most of the time. Usually, it would snap when trying to reverse out of the tube. Once, a piece broke off inside the heating element, so I had to purge several times to get it fully cleared. The worst was when it clogged the nozzle half way through a long print, and it wrapped a huge goop of plastic around the nozzle and heater element! I was so worried it damaged something, and it took a long time to get it all peeled off and cleared. I was lucky there was no damage done to my printer! Needless to say, I haven’t attempted a print with any of the other colors since! I realize it says it’s for 3D pens in the title, however the description clearly states it works with 3D printers as well. So unless you are using this with a 3D pen, or you plan to sit and watch your printer to ensure nothing goes wrong, avoid this filament at all costs!

My son LOVES the 3d pen, and this was a great set of refill fillaments. We oversee the projects because there is heat involved, but it is easy and fun for him, but still challenging He has made a lot of cool things, and this variety set of colors gave him a lot of new ideas and worked well with his 3D pen

Fits 3D pen perfectly

these are strong and long lasting for our 3D scribble pen!

It's a gift so I will definitelybe giving an update. But I dud open it and look inside and it's packaged very nice and smart. ✌️

The product is what we were looking for and works well in his 3D pen. One portion was defective and their customer service exceeded my expectations. We will use this company again when we need more filament.

Good solid filament doesn’t have a problem going through the pen will buy again.

As this is a gift, yet to be given, I can’t evaluate it yet but the abundance if co,or choices was impressive. Hopefully, it will work well.

The refills themselves are fine but this is labelled as 3D Pen with PLA Filament Refills. There is no pen with it, just the refills.

Schöne Farben, lässt sich gut verarbeiten. Leider passen sie nicht in den 3Doodler, egal, wir haben noch einen anderen 3D-Stift, dann werden sie eben ausgetauscht, und der 2. Enkel bekommt dann auch so einen, denn für den 3Doodler bekommt man gefühlt nichts oder sauteuere Nachfüllstäbe. Da sind diese langen Teile 100x besser, man muss auch nicht immer nachfüllen, wenn man gerade mitten in der Arbeit ist. Dieses Nachfüllpack ist definitiv sein Geld wert!

Still have not receive the Bonus 250 Stencils eBook with purchase

Used these for a couple of hours. Great product, no smell and great colours.

Sehen mega schön aus und funktionieren einwandfrei mit dem 3D Stift
