Printed onto sheet aluminium (similar to what a road traffic sign is made from) and available in 3 sizes: A6, A4 and A5. The technique makes the print completely waterproof. Comes with 4 adhesive stickers which will adhere the sign to almost any surface.

My signs are 100% waterproof. They can even be put through a dishwasher with absolutely no fading. They can be hung outdoors and cleaned with water and a cloth. All the advances of a high quality poster but none of the "fragility". 

I can send anywhere in the UK by Royal Mail or International with Ebay Global Shipping.
