Made from high quality 150d polyester material. Each string is 12.7 metres in length and contains 40 pennants; each pennant/flag measures approx. 15cm x 23cm. Suitable for indoor and outdoor use. Note:  Polyester bunting can be used indoors and outdoors but we do not recommend leaving them out in bad weather as their lifespan will be greatly reduced. The Flags are heat cut to give them a clear straight edge and then sewn on to strong polyester tape.
