Geosec slides are made in lincolnshire with modern materials, but are hand finished in the traditional manner.

Mugs, coasters, keyrings and mirrors, plus jewellery items are made by an associate company in Yorkshire using images of slides produced by Geosec. 

Slides made to Order. If you have missed a slide that you wanted to buy, or can see one in the SOLD ITEMS FOR REFERENCE section that you would like to have, Geosec can in most cases make another for you at the same price as the original. For details click here  Made to Order
