Various sizes. Trees pack flat with 2 pieces per tree. CARE INSTRUCTIONS: This sign is made out of mild steel, so we recommend hanging indoors if you want to avoid any chance of rusting! Signs can also be easily weather-protected by coating it with Rustoleum Spray Paint. A slightly damp cloth can be used for fingerprint removal or other markings; dry product quickly as oxidation may occur if water is left on the product for too long. Because we use recycled steel, each piece will be unique and may have slight markings or patina. We recommend hanging most of our signs with velcro 3M command strips! * We offer volume discounts at quantities of 12 or more! CLICK HERE to learn more.
