NONTOXIC 3D Pen Filament Refill Kit - 20 Colors - 500 Feet - Universal 1.75mm PLA Filament - 25’ Per Color - SketchPro

Decent amount of filament for the price. Its anywhere from 30-50 for a full roll of any of the colors so if you need a small amount its perfect. There is no way to tell the quality of the filament or the brand. The items in the box change from box to box and the image on the box does not represent the actual contents or colors in the box... so its hit or miss. You may get a great filament you want more of but buying another box will not get you more of it because there is no consistency to the items.

When my daughter fractured her leg in two places, I was at a loss on what to have her do to prevent total boredom. Well, the answer came to me while cleaning up our craft area and remembered our delivery the day before. I had purchased the Sketchpro filament refills and decided to let her do an activity while I documented it for a review. This is it.I was truly surprised at the amount of filament that was in the box! Lots of pretty colors, but the length seemed true as advertised. Obviously I'm not going to measure each and every strand, but it was plenty. Also what surprised me was that each bundle was individually bagged. Wow! I appreciated that very much. The big decision was which colors to add to her project.Her pattern was a bunny and she decided to layer it. Cool! I'm adding picture of her progress. Now please keep in mind that she was injured and had to take several breaks, but I think she did a fantastic job. There was no smell at all as the filament melted as she worked. I walked across the room and there was some odor there, so it must have drifted away. But I admit, it was not strong at all. The filaments themselves are made of a strong plastic and melted evenly and quickly in the pen. They cooled and set quickly as well. A tiny bit on the brittle side if you make the filament thin, but when done properly it is quite sturdy.I recommend this item highly as you will get what you pay for. As for the seller, they are awesome to deal with! I give them five stars as well! So pick some Sketchpro filaments up and give them as Christmas presents. They are worth it!

It delivered like promised, came with all the different kinds of color and a lot of length for each. The one down side is that the box is a bit smaller than I thought it would be and it wasn't really good for using it to store the material after I took it out.

Absolutely Love this! We've been able to make so many creations having this refill pack. Tons of colors and they're all separated nicely as well. Definitely worth the price, which compared to other places is great! No smell, and burns at the desired temp perfectly. I created stencils and my daughter has made all sorts of little creations! Thank you!

Worked great. I just used all of my black on the first try. I don't want to try other products, since this one did so well in my MYNT3D pen. I wish we could get SketchPro in boxes of black only or favorite color. This is really a fun hobby.

the filament is fine, i wouldn't trust the pen itself to any child and find it impossible to use, filament comes out in very thin strings and breaks into pieces

I haven't used any other filament before, but this stuff works great! I used it in my off-brand 3d stereo drawing pen with no issues.

She has never even used it. Totally not interested.
