A sample only works if it opens with one hand and does not leak into a handbag. TWIN_PACK is a sachet with a patented opening system that can be filled with any liquid substance — cream, gel, shampoo or a perfume sample. Cosmetic samples with your print are produced in full colour across the whole surface, in 50×50, 50×80 and 50×100 mm formats, with a minimum run of 500 pieces.
