We are grateful for your interest in Ohio 4-H Learning Lab Kits! The fastest, least expensive way of replacing lost parts is to use the Educator's Resource Materials Set that comes with each kit. It includes black and white images of the kit's components, from the small tags to the large posters, and everything in between. Whenever possible, images are actual size. If you need in-color replacement parts or large pieces like posters, place a special order here. A customer service representative will call you back with an estimate before you place your order. Thank you!
