I DM'd you regarding a protocol from Brazilian nail expert Marilla Beauty called: "Contact bio gel, or Contact Gel protocol.  Because  after seeing your Instagram you actually pulled off making an easy builder gel extension. Plus you told me where to find clips of the technique!!!   I tried purchasing the Marilla $40 course online which was no english, my goal was to purchase the tool (silicone concave mold used to make builder gel nail extension) nobody is talking to me & I am not versed in Portuguese or espanol.  Would you be willing act as intermediary to ask "@Marilla Beauty" where or how to purchase the tool?  I've tried finding it through "image" google searches unsuccessfully.  The silicone tool is really innovative as it makes the concave in builder gel and releases the extension effortlessly.  I am older senior my hands aren't as steady as when young.  I really need this.  I ordered two peel it gels: cuccio & Markartt both good do you feel like helping me? Thanks for reading my message.
