Your luau party will definitely have that vacation vibe when you have your guests sipping their drinks in these creative luau cups! Each plastic pineapple cup holds 16 ounces. It is 4 inches wide and 5 ½ inches tall. Separate top and bottom pieces fit together to make a complete pineapple-shaped cup, with a hole in the top half fit for a straw. You and your guests will feel like you’re on a tropical island instead of being on your own backyard.
