Product Name: Vintage 12x12x4 shops thick heavy glass block
I remodeling a home built in 1950's and found these glass blocks dividing two rooms on the upper half of the wall I carefully meticulously removed, at no ease, the glass blocks. I'm shops either selling them individually or at a whole. The whole price would be 250 there's 11 total or individually I will sell for $20 piece. These are beautifully preserved very clear nice see through everything is perfect on it like new.
