The popper wallets are made from responsibly sourced recycled post-consumer polypropylene material. They are popular as storage files for loose papers when attending meetings or keeping papers tidy for filing. The large capacity will hold up to 150 pages, and the fold-over flaps with colour-coordinated press-stud closure keep papers secure. The plastic wallets also have a 'Superline' finish, a pen holder cut-out under the curved flap, and include a handy pocket for personalisation and indexing. The pack contains 5 transparent coloured files for easy colour-coordinated filing.
