Refill for UNITS (Single Pack) by Cigma Magic - Trick

Murphy's Magic

Includes a reel of 65-ft single thread.
The tailor-made reel can be disassembled or replaced in a short time.
The single thread can endure 30 grams maximum, which is about the weight of 20 playing cards.
Due to the slight flexibility of the single thread, an object weighing nearly 30 grams will be a bit shaky when it is suspended.
