A great value pack of A3 size (297 x 420 mm) greyboard. Greyboard is ideal for making mock ups, presentations, book making or modelling. The sheets are 1000 micron thick, which is the equivalent of about 1mm. Packs run from 10 to 2000 sheets.
Greyboard is made from 100% recycled material and can be used in many ways: as backing card for packaging, creating displays, model making and mounting art prints. The board is the same grey colour all the way through and on both sides.
Greyboard is a versatile product and the ideal material for model makers, being rigid and sturdy so models last for years. Easy and fun to work with, create handcrafted model scenes (using a small handheld cutting tool) for your mini worlds, model railway or set design.
This thick, strong board is ideal for mounting art prints, displaying finished work or creating a design portfolio. The rigidity of the board protects artwork from creases and folds, dust, bent corners and a small amount of moisture. When used as backing card or in packaging, greyboard is excellent at keeping items flat.
Quick idea! Use greyboard as a backing card for notepads, books and music sheets.
Manufactured in one shade, grey. Shades can differ from batch to batch, as a result of the 100% recycled materials used to make the product.
