Here are 28 used Weck Decora glass blocks, made in Germany. These are all 3 7/8" thick x 7 1/2" square. They are layers 5, 6 and 7 from the bottom in the photo. These 28 blocks are what remains of the batch I bought to make the shower wall shown. They would be great for a greenhouse window, basement window, etc. etc. $5.00 each for a total of $140. You may take some of the foam floor panels seen to pack them in your vehicle as well. I am in Bowser in Deep Bay.
