We create these shelves using the beautiful vintage wood boards taken from decades old shipping pallets. We disassemble the boards from the pallets one by one and then sort them to create the most beautiful color combo according to what you are looking for. We can provide many different colors through stain and assortments by species of wood. Some customers want the same tone throughout the bookshelf and some want a "patchwork" look as shown in this example. Every shelf unit is made to order so do not be afraid to ask for the dimension you want through Chairish Support. Shipped partially assembled. Priced accordingly to your dimensions.
