I wouldn't mind if you were able to quickly knock a couple off to see what they were stuck on like before quoting for removal, but that ain't really possible either, as I've had with the looks of it, 3 different adhesives used on my bathroom walls when it had last been tiled.
Some came off brilliantly, some quite hard and others just bit at a time as they had been fixed with different adhesives, even on the same flippin wall for cryin out loude, lol
