Mental Prediction Board This is a mini-sized Mental Prediction Board. It's a prediction board that uses a chalkboard and chalk, and it's a mini type suitable for close-up magic. It has been used a few times. You can predict three things simultaneously. Because of its small size, you're limited to simple symbols (☆) and playing card suits and numbers (♡7), but it's surprisingly well-made, so it won't be noticed in close-up magic unless you hand over the prop. ※ The playing cards in the second photo are for size comparison and are not included.
