I am facing a problem from birth that I can't twist my hand, I have said this to the support but I need answers from you guys. If I can't do a magic trick as I am in a condition where I can't do it. Will the theory11 support team help me by giving me another trick for free as that would be saving money instead of not be able to do it and I can't do anything about it. My question to you is that if theory11 will allow me to do an exchange. Please tell me, thanks!
