Quick service and the best gaffer tape in the business. Thanks
Website is easy to navigate although information on the products could be improved. Other than this the order arrived very quickly.
Purchase experience was fine, delivery time was a bit on the slow side taking 7 days to arrive. Otherwise all ok, product is fine.
