Designed for rainy day work, this umbrella measures rainfall in inches and/or centimeters, both shown in large, easy-to-see lettering. Molded in sturdy, impact plastic; the non-glass tube is plastic which won't break if dropped. May be attached to a post or inserted in garden soil (mounting screws are not supplied).
