Hi all,A while ago, we got a 3Doodler Start as a donation and we added it to our collection as a STEM Kit. But both of the pens have now broken and it hasn't seen a whole lot of use so we decided to weed it. But we have 8 packets of the filament still remaining so if anyone has the 3Doodler Start, we'd happily send you some refills. We have 8 packs of 24 filaments in orange, yellow, blue, red, white, and green. Let us know if you ant them and we'll send them to you!
