This package includes a Poster Browser Frame (with a capacity of 40 sleeves) together with 15 Classic Poster Sleeves. Additional sleeves can then be purchased seperately. The sleeves measure 30″ x 40″ but please note that these are external dimensions and 1″ greater, on each of the four sides, than the poster which they will hold. The steel frame is very easy to slot together and comes complete with castors in a choice of colours. The sleeves are in one piece, acid free and ant-static. They are edged in strong fabric which comes in a choice of colours. The corners are reinforced and the clear plastic screen has a seperator within it to allow two posters to be displayed back to back. Units can be made to measure.
