Over 20 years of field testing and customer use. With test information gathered over the years, laboratory test data and the experience of having over ten million of our markers in service throughout the UK, US and six other countries, our marking system is the most thoroughly tested available. We gladly offer references so that you can talk to our satisfied customers. Our markers are less expensive than brass or ceramic or thermal plastic, won’t crack and crumble (ceramic), won’t bend exposing sharp edges (aluminium), won’t tarnish (brass), and have no scrap value (brass & aluminium). They have brilliant graphics tested for UV resistance and are available in non-reflective or reflective in just about any size, shape, or colour imaginable.
