Polished nickel silver finish, simple sash keeper (we made that name up out of thin air). This belt buckle style looks like something you’d run a scarf through or maybe a length of rope, just like Jethro used to hold up his dungarees.
BKL-226 is solid cast nickel, bright silver finish, and the holes you see are about 1-1/4″ and 7/8″ in diameter.
BKL-226  $5 each or 10 for $20, USA shipping included
