A mixture of hardwood and laminate. New includes bamboo, wire brushed oak, cotton valley oak, & hickory. We opened the 1st few to get started but never actually did. They've been setting in those boxes the whole time. The used pieces we bought used but are still in great shape but we're unsure of what kind they are. We have been buying these whenever we could afford it for our house. Due to health issues we are unable to keep them any longer. We're only asking for a fraction of what we paid and are open to reasonable offers. Unreasonable offers will be reported.
