I'm not sure if this topic is reffering to Sam's Switcher or another kind of Switcher.
Anyway with regards to Sam's Switcher I've just recieved this from
http://www.topsecretmagic.co.uk/main.html (Speedy service by the way)
£4 for four.
Basically it's an envelope, small pay packet type. The quality is excellent, these are gonna last a fair few uses & at a pound each they ain't expensive. They come with detailed instructions & approx 10 or so routines/tricks which at this point I haven't read. Paper, playing/esp cards of similar can be vanished or changed or they can be used for reveals.
Definatly worth £4 of anyones money. For what it is & how it works 10/10
