MINI SPIRIT SLATES PLUS BY TCC, CONAN LIU ROYCE LUO Main Effect: Two slates (Outer Dimensions 11cm x 15cm, Writable Area 8cm x 12cm) are displayed and placed together. A volunteer is asked to "randomly" select an object (for example, a playing card from a deck of cards). The 'spirits' know the information he/she selected! Upon opening the slates there is the selected card written in chalk! Completely Silent: Due to the uniquely designed internal mechanism, our version is not only 'quiet' but completely silent! You will never hear anything when the gimmick triggers! Fully automatic operation: And the entire operation is self-working. You will only need to place these two slates together and the magic will automatically happen! No suspicious turnover moves or shaking like what was required with traditional versions of this classic prop! 10-second reset; electronics free; one-man operation. This will be the best Spirit Slates you will ever find for your show or collection. Compact size: Lightweight and portable, suitable for close performances.There used to be smaller versions made of plastic, however, due to the size being too small and made of plastic, they looked too much like toys. The size of the Mini Spirit Slates takes into account the needs of portability, feel, visibility etc. Made of Professional High-quality Blackboard, with hand polished Real Black Walnut frame. Outer Dimensions: 11cm x 15cm Writable Area: 8cm x 12cm In view of the above, the Mini Spirit Slates is actually also suitable for some effects apart from chalk predictions, such as the appearance of cards in the middle, card corners, notes, torn pages... the possibilities are only limited by your imagination. The delicate workmanship and clever mechanism make this suitable for close-up performances. The black walnut and finish make this also suitable for magic collectors.
