Proline Biodegradable Flags and Staffs are today’s most environmentally friendly marking solution. These flags are made of non-woven rayon cellulosic material derived from wood pulp.

They are completely non-toxic to humans, animals and the environment. Biodegradable Flag Staffs are constructed of wood (24″ length) which promises complete degradation in six to twenty-four months depending on the climate and environmental conditions.

Biodegradable Flags can be printed with a custom message. Call us to search our extensive legend library or allow us to assist in the creation of your own by calling a Presco sales representative today!
