The quick witted and mischievous monkey is featured on our Monkeys Personal Checks. There are many types of primates that can generally be classified into 3 categories- New World Monkeys, Old World Monkeys, and Apes. Monkeys range in size from the tiny pygmy marmoset at around 5-6 inches long to the Mandrill which is over 3 feet long. Some live in trees and eat leave, some have tails and some eat snails. Monkeys are all about variety! Put some variety in your life with Monkeys Personal Checks, available in single and duplicate check format. Matching address labels and a coordinating checkbook cover are also available.
