Hi there! Thank you for your question. Unfortunately this is an older project and was completed before Erin acquired the business as the new owner. Our thought is that the floating shelves were custom built for this project. However, we have recently been using two manufactures who ship the shelving and hardware, ready to install. Linked is the manufactures we have been using, Ultra Shelf and Shelfology. Both companies allow you to order per your desired finish and needed size.
