Best toy ever! Would sooo buy again and have so much fun with it I also bought another virsion from the same buyer to get a bigger big and I am now getting a nothing one for my brother cause we love it soooo much thank you!It was requested for her birthday by my 8 year old granddaughter. She was pleased. Mission accomplished.This is too cool! I love taking apart the pen and putting the parts back together in different configurations. I can’t stop playing with it! The magnets are pretty strong, so I can pick up almost all the balls at once. It functions both as a pen and as a toy, and the ink is smooth and doesn’t smudge. It also comes with several ink refills. If I take it to work I will get nothing done all day. These will make a fantastic gift.The polar fidget pen is no doubtly one of the best purchases I've made. I recieved a gold pen and was pleasantly surprised by the new sleeker packaging vs the more basic original packaging (new on left, old on right) and was ecstatic to see my suggestion on adding some step by steps was taken into consideration as seen on the card which can also lead you to their youtube simply by typing in Polar Fidget Pen and instructional videos are there. I also love that theres additional information about the pen on the back of that card. The ink also flows so smoothly which is great for my sketches. 10/10 would buy again.Exactly what we wantedThe Polar Pen was a great buy!!!Holds up well and is great to fidget with!I love it how it help me release my stress but the ink goes everywhere sAll the magnets broke after 20 minutes! Do not waste your moneyNo me gusto que llegara la caja rota y pedi el colorido y me mandaron el negro.X otro lado la pluma funciona bien e igual todo funciona bien.Bueno peti
