I've bought this effect twice. Firstly from another website, and then again from Penguin Magic
because of their superior customer service.
Upon first receiving them I knew this was one of
those props I could always have on me and that was a nice kicker to SWTC by Jay Noblezada or many
other card tricks The glasses pass as realisitic and I immediately wore them as if they were
prescribed. However one late night I jolted up from slumber and stepped and crushed them.
Slightly less impressed by the two reveals in the penguin model on my next purchase compared to
the four in the others but have been told penguin is now selling the four reveal models which I
intend to buy again since the penguin pair snapped in half while in my pocket.
Great gimmick so
real you should treat them with the care of real glasses and keep them in the case if not on your
face.
UPDATE!
As earlier stated I really liked this trick. I bought it from a now defunct company and couldnt be happier. Broke them with one wrong step. The next pair I bought for cheaper from penguin but only two reveals were existing. Manufacture malfunction number one. The frames then snapped in half.
Just bought third pair glumps of plastic excess on frames from the molding process during manufacturing. Screws attaching arms to fram are uncut and have drawn blood and the reveals, while four were actually present as advert claims they are in different order than the first pair I purchesed, which I preferred.
I really like this effect and spin on ghost th lass just need to churn out consistent a model. Loses a star.
