The Maine State Showroom’s “spring spectacular” sale begins Sunday and runs through April 21. During the sale, all in-stock products are marked down 25 percent.

The store sells a wide range of wood products ranging from bureaus and bookcases to ship models and cutting boards made in the wood shop at the Maine State Prison in Warren. The store’s located on Route 1 in Thomaston, near the site of the old state prison before it was demolished a decade ago.

The Department of Corrections says the store has annual sales of about $1.5 million.
