Stamps 40mm XL 6 Stock Frame A3 Portrait Display


Our Mountame stamp stock frames are the first of their kind. Our unique engineering gives you not only the freedom of creativity with layout options and collection types, but they are also glueless and therefore prevent potential contaminate transmission. Whether you are collecting thematic or regional collections, you can rest assured that your stamps are in the best preservation grade frame possible.

This A3 portrait frame uses InvisaWallet™ technology for its 40mm high stocks, each stock, 6 stocks in total contains our InvisaWallet™ Inserts. These inserts are alkali buffered which acts as an anti-ageing agent extending the life of your stamps when in direct contact. Furthermore, our InvisaWallet™ film is crystal clear and inert, not only giving you the best clarity for your collections presentation, but it also shields the stamp face.

The 40mm stock height is ideal for both Commemorative and medium Definitive stamp sizes; for collections such as the famous George V Seahorse high values, but not exclusive to. The frame stocks can handle greater size stamps, but we advise that you consider a greater stock size, as any stamp outside of the stock containment will not be in contact with our InvisaWallet™ Inserts, and therefore not protected. We currently do not offer an off the shelf solution above 40mm. However, we can create any stock size on request for taller stamps such as verticals and the £10 Britannia postage stamp.

When framing valuables, or investments we always recommend upgrading to the PLEXIGLAS Gallery® UV 100 for UV Protection, and keeping your frame out of direct light.
