Magic Silk handkerchiefs are a key element to many vanishing acts and other magical illusions. The colorful Red silk can be made to appear, disappear, swap and change colors as part of your magic performance. Silks are extremely compact to compress into small spaces and are made to withstand heavy use, including frequent twisting, rolling and knotting. Each silk square measures 24 inches. Multiple Magic Silks can be used together for tricks requiring more than one silk.
