Chinese red‎ dragon and black geometry design square 8 pillowcases 16 x16

Unbranded 4 red and 4 black square pillowcases I am unsure of the material - could be silk? or polyester? unsure These pillowcases are square and measure about 16 x 16 Zipper on one side The red pillowcases are red with gold dragon print The black pillowcases are black with red geometry designs These are beautiful and would make a great style to any room I believe these are homemade - there are no tags located on any pillowcase
