I have 128 used glass block. They are dirty from storage and some have some silicone still on some of them from when they were used. Most of them are in great condition but some do have nicks and chips or maybe a crack. Most of the defects are small and would not affect use.
I will take $2.00 each, or $256.00, if you take all of them.
If you want to pick and choose and only take a few they will be $5.00 each.
