4mm Corrugated Plastic Sheets, Short Flute, 24" width x 18" high. Light-weight PolyPro plastic ideal for temporary signage. Used in many sign applications, these blank sheets are great for screen printing and vinyl adhesives. Made in USA, these durable corrugated plastic are the modern standard for yard signs, cut-out signs, and more. Available in white and yellow.

"Short flute" refers to the orientation of the sign. Fluting always runs vertically with a sign (so the stake struts can be inserted into it). Short flute means that the sheet is wider than it is tall. You may use these signs horizontally with yard stakes (sold separately).
