This useful little glass is a great tool for measuring liquids in either teaspoons, tablespoons, ounces, or milliliters. It has markings for each measurement and also features the Aquarium Co-Op logo on the front in green. 

If you like to have all things Aquarium Co-Op, this is a great piece to collect. Especially useful for more accurate dosing when it comes to medications, dechlorinator, fertilizers and much more. Works well as a small gift or stocking stuffer for the true Aquarium Co-Op fan.
