Thanks Damian - that is actually one of the ones I’d already seen as it turns out, but I was surprised by the price as it’s a whisker under a hundred quid to get one 45cm x70cm which isn’t exactly enormous.

Maybe it’s just the case that the 2 way mirror process they add is very costly, as it’d be about a 10th of that cost to just get a piece of glass cut that size.

Bit of a bugger though as I wasn’t expecting to pay nearly a hundred quid just for a pane of mirror glass. :(
