Steven posted 07/13/2018 Are you one of those people who passed up on BLOCK-OFF thinking that it’s no big deal and not a very impressive trick? WRONG!!! It happens to be a terrific little effect with the usual very cool apparatus we have come to know from 3D Magic Works. Easy to learn and perform. Perfect to carry around with you and perform at a moment’s notice. Did I mention very affordable? Go for it! That will be all for now. Thank you for listening.
