I bought this 3D pen not knowing excalty what to expect! I opened the package and within 60 seconds I was already creating super cool 3D art! (it is addicting!) My adult sons (both of them), their wives, my husband, literally everyone who sees it has tried and LOVED it! We have created houses, stick figures, 3D names, and lots more! Now they all want one too! I also plan to purchase these for the artists in the family beacuse I am excited to see what they can do with such a cool tool!
