Black Twin Sheet Set

NWOT. Sheets are a matte black with a black satin-like trimming. Can't recall where I purchased them, it's been decades but I noticed the stitching isn't the best so it was probably Walmart. 60% cotton, 40% polyester. There are actually two pillowcases included, despite it being a twin set. Purchased for use on my old bed, never used as I ended up moving to a bigger bed. Pet friendly home but kept in spare room. Wood background is dining table, not the floor.
