Package includes: 10 x Blank Yard Signs Review: Decent corrugated plastic for "do it yourself" projects - Corrugated Plastic is essentially glorified cardboard. However, corrugated plastic is made out of plastic, instead of the paper used to make normal cardboard. This results in a product that has several advantages vs normal sheets of cardboard. Specifiically corrugated plasic lasts longer than normal cardboard, is more resistent to normal damage than regular cardboard, and more resistent to water damage (i.e. the plastic doesn't get water logged). However, corrugated plastic is still almost as light as normal cardboard, and also almost as easy to cut to size. This makes corrugatated plastic a good choice for some "do it yourself" projects. In my case I needed a little material to make a small "shield" to protect some control buttons (on a power supply I owned) from the cats stepping on those buttons (thereby changing the power supply's settings). Since I didn't need a large shield (just one big enough to easily cover the power supply buttons), I figured corrugated plastic was a good choice (as it is VERY EASY to cut the proper size and shape). Since I couldn't find any old corrugated plastic around the house, I bought this set from desertcart. Yes, this set was sold for making yard signs (and it would likely work well for that purpose), but since these are still corrugated plastic sheets I could easily cut down one of these sheets to make my power supply button shield (which I then attached to the power supply with double-sided tape, with duct tape covering the top of my "shield"). Review: Good Buy - very sturdy and reasonably priced for as heavy as it is. Good stuff. ## Features - Size: 18 inches tall x 12 inches wide, 4 mm thick. - Good Material: Made of high quality corrugated plastic yard board, durable, waterproof and reusable. - Ideal for Advertising, Rent, Garage Sales, Open House, Parties, Estate Sale, Lawn Signs and DIY. - Convenient Size: You can cut and fold the corrugated plastic signs to meet your preferred size and shape. - What you get: 10 pieces bland yard signs. ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B0CQLZK3B1 | | Best Sellers Rank | #16,319 in Patio, Lawn & Garden ( See Top 100 in Patio, Lawn & Garden ) #83 in Yard Signs | | Brand Name | Newflager | | Color | White | | Customer Reviews | 4.6 4.6 out of 5 stars (278) | | Included Components | Blank Yard Signs | | Item Dimensions L x W | 18"L x 12"W | | Item Thickness | 4 Millimeters | | Item Weight | 1.05 Kilograms | | Manufacturer | Newflager | | Material | Plastic | | Model Number | 18-12 | | Mounting Type | Ground Mount | | Orientation | Landscape | | Part Number | 18-12 | | Pre Printed Text | 10 Pack | | Size | 18 x 12 | | Style | Modern | | Unit Count | 10.0 Count | ## Product Details - **Brand:** Newflager - **Color:** White - **Material:** Plastic - **Mounting Type:** Ground Mount - **Product Dimensions:** 18"L x 12"W ## Images ![10 Pack 18'' x 12'' White Corrugated Plastic Sign Blank Board Double Sided for Garage Sale, Rent, Birthday Party, Guidepost Decorations - Image 1](https://m.media-amazon.com/images/I/51c23MLSVML.jpg) ## Customer Reviews ### ⭐⭐⭐⭐⭐ Decent corrugated plastic for "do it yourself" projects *by A***R on November 3, 2025* Corrugated Plastic is essentially glorified cardboard.

Good stuff. ### ⭐⭐⭐⭐⭐ Signs for the Times *by A***. on January 23, 2026* These plastic pieces are perfect for protest signs. I had a friend staple lathe strips to them for handles. The surface is easy to letter on. They are sturdy and hold up in rainy weather.
