'HORROR BAGS BATS BOX'

I remember this box for sale on ebay some months ago and I was going to bid for it but it was a little too much for me at the time, but I suppose you would expect something as obscure as this to be not cheap, I think it was about 25 pounds. I had nether heard of Bats in the Horror bag range before and I haven't seen any pictures of the packets either, maybe someone knows something about them. The picture shows the side and front of the box.

Thanks to Darren for the scan
