With these bold acrylic fish glasses, you'll be making a splash! Each glass features a school of swimming fish and a smooth rim for stylish sipping. The Double Old Fashion and Tumbler each hold 16 and 19 ounces, respectively. Not only are these glasses shatterproof, but they're also safe to wash on the top-rack of your dishwasher. For longer lasting use, opt for hand-washing with a gentle sponge and steer clear of harsh cleaning products.
