What parents say


“Bought the pen for my son’s birthday and this pack a week later. Should have got them together — he flew through the starter strands.” — Rebecca M., Verified Buyer

“Great colours and it doesn’t jam the pen like the cheap ones we tried. The twins share it without wars — there’s that much of it.” — Daniel K., Verified Buyer

“Went in the Christmas stocking next to the pen. Best-value part of the whole gift, honestly.” — Priya S., Verified Buyer

Frequently asked questions

Will this work with the InnoSketch™ 3D Pen?

Yes — perfectly. It’s standard 1.75 mm PLA, exactly what the InnoSketch™ pen is designed for, and it also fits all standard high-temp (200°C) 3D pens.

How many colours do I get?

Twenty vibrant colours per pack, drawn from a wider palette of thirty — plenty of variety for multi-colour creations.

Is the material safe for kids to use?

It’s non-toxic, biodegradable PLA. As with any heated 3D pen, we recommend adult supervision for younger children while the pen is in use.

How long does a pack last?

With roughly 338 g of filament across 20 strands, most young creators get weeks to months of regular drawing from one pack.

Does it clog the pen?

The PLA formula is made to flow smoothly and resist clogging — one of the main reasons we chose this pack over cheaper alternatives.
