These vine protectors are like milk cartons without the print.
We have two sizes, 20in. drop-ons and 24in. wrap around.
The 24" white ones are poly-coated on two sides (like milk cartons but all white) with a 3.75" diameter. You wrap these around the plant (for when the plant is too tall to use the drop-ons) and staple together. They are treated to withstand water and weather conditions for 1-2 years.
