Aluminum tags are a durable labeling system for marking trees, plants or anything that requires identification. Each write-on tag is made from a .005" aluminum stock wrapped all the way around a stiff cardboard backing. This backing allows for easy marking with pen, pencil or sharp pointed object. Embossing lasts for years, even under harsh conditions. Tags measure 3/4" wide x 3" long. Each box contains 500 tags and corresponding wire ties for securing to object. Made in the USA.
