The SF protective mounts made of plasticiser-free, crystal-clear, anti-reflective polystyrene film are glued to the album cardboard in the size of the stamp pre-print. The mounts hold the stamps exactly in place and prevent them from sticking together. At the same time, they offer optimum protection against dust and damage.
In the case of similar stamps that differ in colour, perforation or printing technique, for example, the individual special features are noted on the respective album sheet. This only applies to stamps with Michel main numbers. This may also include the year. Lighthouse always pays attention to a harmonious and aesthetic overall appearance of the SF album pages.
