3D Pen Filament Refills - 14 vibrant colors including 4 glow-in-the-dark and FREE Stencils eBook - 1.75mm ABS filament - 280 Linear Feet Must have for anyone who owns a 3D printer pen!

Buyer Beware! What you receive doesn’t look anything like the picture. The picture gives you the impression that you will receive these coiled filament in a nice circle and there is lots of filament there. The package that I received is in a vacuum sealed bag. It does not resembled this ad picture. If it were not a gift for my grandson, I would open the package and measure the coils. This has happen once before where the pictures displayed are implying that the picture is the size of the item, in my case it was silicone molds for baking and soap making projects. So ...Buyer Beware....it might look like a good deal but it doesn’t measure up to the hype!

After the disappointing crappy 1st 3D pen we got it was nice to actually receive a good product! These are nice long strands of filament and a nice selection of colors. My godson who has used many different brands even commented on how nice it was to get such long strand of filament. He is happily using them up with his nice new 3D pen!

We purchased this filament refill package to go with a 3D pen for my 10-year-old daughter's birthday. The colors were as depicted--bright and fun. She loved the glow-in-the-dark filament. They work well with the pen we bought. She is very pleased. After working with it all day yesterday, she's only used up 1 full coil and a partial coil, so it doesn't deplete too quickly.

This is a great, quality set of refill filament for a 3D pen that uses 1.75mm. The wide range of colors are great and even include four different glow in the dark! They came in a nice gift worthy package, were vacuum sealed, and each color was individually zip tied. They were easy to snip off. I will definitely be ordering this set again! My 10 year old is already running out of some colors because he is using the 3D pen everyday this summer.

Totally disappointed that this does not fit the 3doodler pens. I searched for “3doodler” products on amazon and this was the “sponsored product” by amazon. Ordered it and my poor daughter waited paitiently for this, one it arrived we tried it right away and the filament is too thin for the pen. I have not tried to return a product yet but this will be my first. Wouldn’t have been so upset if it wasn’t the search engine that suggested this specific product for the 3doodler.

I'm not sure what can be said about filament refills for a 3D pen . . . but these seem to be exactly as described. It is a nice collection of a lot of colors, which is what I was shooting for. I purchased 3D pens for my nieces, and wanted them to have lots of colors to play with. I suspect that they will get tired of playing with them before the filament runs out.All that is really necessary is that it is the right size and ABS . . . which these seem to be. Not much else can be said.

We had to return this product because it does not work in all 3D pens. My son was very disappointed that this filament doesn't seem to warm up enough to soften and then use to do his drawings. It fit into the pen but when it came out it wouldn't stick to the paper and kept get tangled within itself.

I can't give this a bad review, because the mistake was mine. I assumed 1.75 PLA was the same or similar, one brand from another, so I bought this to have some variety with my 3D printer. Not a good idea - it didn't adhere, layer to layer.
