    Trade Customer Success Story
    “Working with Rainbow Safety has transformed our safety sign sales.”

    With the support and marketing tools provided, our sales have grown to over £3,000 per month.

    Fire extinguisher servicing margins are not what they used to be, so supplying safety signs has become a valuable additional revenue stream for our business. On one warehouse safety survey alone we £5,100 in a single order.

    The sign does exactly what we needed for our workplace safety requirements. Packaging could have been slightly better, but the product itself is decent.

    Good quality sign that was easy to install and highly visible. The material feels durable, although delivery took a little longer than expected.
