There are many effects that require the vanish of a borrowed ring. This special handkerchief enables you to vanish a wedding ring or similar type in a very easy and convincing manner, and later reproduce the ring from another prop.
Please note that with this handkerchief, you do not have to tuck a corner of the handkerchief under the middle, which is not a very natural way of covering a ring.
The ring is not sewn into a corner of the handkerchief.
A useful accessory to use with many trick boxes.
