We have used large amounts of stick labels over the years. The common yellow wood ones keep for 1 to 3 seasons tops and are often treated with pesticides to withstand rot. The white, durable, plastic labels from Rainbow products, England have made life easier for us. They keep for many years (until a tool breaks one by mistake). They are easy to write on with a pen of waterproof colour. These sticks do not rot and are easy to keep clean. Their size is 160x14 mm with a hole at one end. A package contains 50 sticks.
