Great colors and keeps the 3D doodling chaos going
These refills worked well and the color variety is great. The kids loved having so many options, and it kept the 3D pen fun going much longer without anyone immediately yelling that we were out of the “good colors.” A true household miracle.They fit as expected, fed through the pen well, and were good quality for creative projects. Great value if your kids are into 3D doodling, crafting, or turning your kitchen table into a tiny plastic engineering lab.

Tons of Refills, Great Colors
These 3D pen refills are a great addition if you already have the 3Doodler Start+! The variety of colors is awesome—lots of fun options that keep kids (and adults) creative and engaged.The plastic feeds smoothly through the pen and works perfectly with the low-temperature design, which is great for safety and ease of use. The colors come out vibrant, and we haven’t had any issues with clogging or inconsistency.Overall, a solid refill pack with plenty of color variety—perfect for keeping the creativity going without constantly needing to reorder!

Wildly Creative and Safe Fun!!
This doodler pen makes a wonderful gift for the young artist. The Pen comes in 2 sizes,one for littler hands 5-10 or so. The larger one for teens to adults. 3 D art is amazing! I've watched as an 8 year old made pine trees, fences, plants and what looks like a bear! Along with the pen we bought the carrying case a mat with grid lines, another small book of design ideas and additional colored sticks. All made by the same company. It comes with some extra sticks in various colors., a chargeing cord and a small paper book of designs. The pen uses colored straws with a low melting temperature . Works by inserting the sticks into the pen where it melts them at a much reduced temperature. The pen doesn't get hot in the process.

Great price for continued fun
My granddaughter wanted a 3-D pen for her 9th birthday. She received 3-Doodler Start +, refills and case. She has been very busy making new creations. Hours of fun.

Works well in 3d pen and good array of colours
32 different colours for the 3d doodler pen. Lots of different colours to choose from for any creation. Comes in a large pack so will last long. Easy to use and insert into the 3d pen, little difference to the other ones we have used before. Great quality.

Glows as Promised, Smells Worse—Fun but Needs Ventilation and Realistic Expectations
Design & Build Quality🧰 This 100-piece filament refill pack is well-cut and consistent in size. Each stick is made for the 3Doodler Start+ and comes in a soft pastel shade that’s attractive even in normal light. The resealable pouch is a practical touch, helping keep unused pieces dry and organized. That said, the plastic quality feels generic, with no markings or identifiers on the sticks themselves.Ease of Use🔧 These filaments fit the 3Doodler Start+ without issue, but only that model. The 2.5mm diameter is completely incompatible with standard 3D pens. If you don’t own a 3Doodler Start+, this won’t work for you—there’s no workaround. Feeding is smooth, and there's no sign of jamming if your pen is in good shape.Performance in Real Life✨ The glow effect works, especially for the yellow and green filaments, which charge quickly and emit the strongest light. After even brief exposure—like 5 minutes under a flashlight—they glow brightly at first. However, the glow fades significantly within an hour regardless of how long you charge them.🎨 The plastic color has almost no relation to the glow color. Even purple or blue pieces glow in a generic green-yellow tone. Still fun for kids, just don’t expect vivid, color-accurate effects.Notable Issues⚠️ The filaments emit a strong, unpleasant smell when melting. While this is common with PCL plastic, this batch is worse than average. It’s not unbearable, but it’s sharp and chemical enough to be a concern—definitely use in a ventilated space.🚫 These won’t work in any other brand of pen. Compatibility is extremely limited, and there’s no warning label on the sticks themselves. You must keep the packaging or risk confusing them with other filament types.Final Verdict📌 If your child already has a 3Doodler Start+ and you want to add some creative glow-in-the-dark fun, this refill pack is a good, reasonably priced option—with caveats. The glow is brief but effective. The smell is unpleasant but manageable with airflow.💡 Buy this only if you’re fully committed to the 3Doodler Start+ ecosystem and have a safe workspace. Otherwise, look for safer or more versatile alternatives. Recommended with reservations.
