Coroplast, or corrogated plastic, is designed for use with H stakes and can be inserted into grass or dirt wherever you want to advertise. Also referred to as directional or yard signs, this style of repositionable signage is most cost-effective in large quantities, but we can produce as few as one and as many as 500. We offer competitive pricing on both 1-color and full-color signs and can produce custom graphics to fit your needs.
