This is a stained-glass style bottle opener that my mother received from an acquaintance as a souvenir from Nagasaki. It's made of sturdy metal and can be used as a bottle opener, of course, but the stained-glass design is also stylish, making it a lovely decorative item. The box is crushed, but the contents are in good condition. It's also recommended for collections of retro goods and local souvenirs!
