@alexis Here Iñaki Martínez, Unliftable's creator. Thanks for your kind review. I patented this concept in 2018. With Thinking paradox we made a tutorial and Tenyo based his 2020 collection on my concept. Now with the collaboration of Javier Franco from Magic pro ideas I decided to manufacturate it personally. To improve the appearance of the shine you can see a contribution from a French colleague who is in the tutorial QR, With the cellophane of the deck. It improves everything. Any questions here you have me. Thank you
