3Doodler Start 3D Printing Filament Refill Bundle (250 pieces) pack of 1

Alright, so let's talk about the stuff that makes the 3Doodler pen tick – the filament. This colorful string is what brings your 3D creations to life, and we're gonna break down how cool (or not) it really is.First off, major props for the rainbow of colors. Seriously, they've got everything from bold shades to glow-in-the-dark vibes. It's like a candy store, but for your 3D pen. Want to make a neon pink unicorn? Go for it. The variety is a game-changer for adding that extra pop to your designs.Now, onto the nitty-gritty – how well does it actually work? Well, the 3Doodler filament is like the reliable buddy who always has your back. It flows smooth, no weird hiccups, and there's minimal drama with clogs. Perfect for when you're trying to nail those intricate designs without pulling your hair out.What's also rad is that this filament plays nice with different surfaces. Whether you're doodling on paper, glass, or plastic, it sticks like glue. That means you can get creative on pretty much anything lying around. It's all about that versatility, my friend.And let's not forget the ease of use – loading this stuff up is a breeze. Switching colors? No big deal. Plus, the filament cools down super fast, so you're not stuck waiting around. That means more time creating and less time twiddling your thumbs.Durability-wise, it's a champ. Your creations don't crumble like a house of cards. This is key, especially if you're into building stuff that needs to stand the test of time.But, gotta spill the tea on one thing – some folks have noticed the filament's diameter playing a little loose. It's like it can't decide if it wants to be thick or thin. Not a deal-breaker for most, but something to keep in mind for those perfectionist projects.To wrap it up, the 3Doodler filament is the real MVP of this creative party. With its funky colors, smooth flow, and chill vibes, it's a hit for anyone rocking the 3Doodler pen. Sure, there might be a tiny hiccup with diameter consistency, but overall, it's the buddy you want by your side when you're in the 3D printing game.So yes, totally recommend the original filament compared to some of the knock off items available. Have fun

Quality seems good, kids used it up and didn’t complain! No issues in the pen at all!

I don't really understand why these are so cool, but my girls love them with their 3d pen. They do the job (whatever that is LOL)!

Got this for a 11 year old boy for Christmas. Great pack with multi colors. Easy to use.

These are great grandson loves creating things with his pen and these refills are just perfect

My granddaughter loved it.

Perfect addition to my son's 3D doodler. He can now doodle to his heart's content.

I use my 3Doodler for repairing and joining my other 3D printed projects. That takes a lot of filament.While there are many brands of filament that theoretically fit the Doodler, in practice most of them do not feed right or have issues with the temperature range of the 3Doodler.These filament sticks are perfect, and they are significantly less expensive than some of the other, non-compatible brands.I am a fan.One nit, I would have picked another set of colors under perfect circumstances, but for the price, I cannot be too choosey.
