We recently removed these bricks from our front porch. We saved most of them (245). The size is 8"length 4"wide and 1 1/2" thick. We consulted a brick mfg co, and were told they are the type of brick to be used in a commercial kitchen, where they are cleaned daily. They are smooth on the top. Pictures show the top and the bottom. They are all in reusable condition. Asking $245 for all, or best offer. Serious Inquiries Only Please!
