Use the Jumbo Under The Hood Sign to grab the attention of potential customers driving by. Just open the car hood and place the sign under the open hood for an easy advertising solution. These signs are made of heavy duty corrugated plastic that will last an entire season. The signs are flexible enough to fit under most hoods but are NOT designed to hold the hood up by itself! Kit includes (4) panels with (1) letter per panel to spell 'SALE'.
