Glass Block - Used (architectural)

These are used glass blocks 7.75" x 7.75" x 4". They have an R value of 2.08 and they are in very good condition. These cost $8-$10 each new. I am selling for $1.00 each! Any quantity you need (up to 5,000), I can place on skids for pickup or shipping and can deliver locally for an additional fee (to be determined based on location).
