With this specially gimmicked and prepared card, you are able to link it to a borrowed glass unnoticed in 3-5 seconds. The edges (which is very important for me) are completely intact and have no cracks. The card can be presented firmly linked to the glass as a souvenir.
What the video hides at the lower edge would normally be hidden behind a box, book, silk, or some other visual obstruction.
