Lovely unusual and difficult to find pieces of sea concrete which were beach combed on the East coast of Scotland, mainly from Dunbar and Belhaven beaches in East Lothian so they were once in the North Sea. There are 6 bits of it weighing around 1.61 Kilograms. The two-pence piece and ruler are there to give you an idea of the size and the pictures are each the size of a piece of A4 paper (the additional pictures shows both sides of them alternative ways up on different coloured backgrounds and in different lights). These make good art and drawing subjects as there is a good variety of textures and shapes within them and are ideal for using in place of stones and pebbles in outdoor & indoor decor, water features and for art displays and craft projects- especially if your going for a beach, nautical, found, ocean conservation, ensemblage or seaside theme. Postal discount for multiple purchases where Royal Mail weight and dimension limits allow (they usually do); You can either request a combined invoice at checkout or if you pay too much postage and packing I`ll refund any over payment ASAP. Alternatively  you can ask me for an estimate before you decide so do have a look at my other beach combed items for sale. Thanks for looking.
