Do these cabnets have a finished coat on them? Are they made with plywood or particle board?

Hello Ange- Thank you for your inquiry. The Branson Hickory cabinets are natural hickory. No stain or topcoat has been applied. As far as the construction, the drawer boxes are wood with side mount guides they have an engineered wood shelf, a particle board box with adjustable hinges and a solid face frame. Thank you, Project Source.
