Easily identify your keys with these color-coded, write-on key identifiers. Bands are made of heat-shrink plastic and separate keys by color. Slide band over key head and apply heat. The band shrinks to form-fit the key head, providing a writable surface. To label, use a ballpoint pen or a preprinted label. Ideal for awkwardly shaped keys, when standard keycaps will not work. Bands shrink to fit keys, reducing bulk around the key chain. Two sizes are available: Medium and Large. Size Medium is ideal for standard-size keys, such as house keys. Size Large is ideal for larger-headed keys, such as office keys. Made in the USA.
