The Slyk A5 refillable cahier notebook features a recycled plastic cover with an elastic band closure that securely holds two internal cahiers—one dotted and one lined. Each cahier includes 32 cream-coloured sheets made from 70 g/m² paper, with rounded corners and visible spine stitching for a handcrafted look. The covers of the cahiers are made from cardboard. Cahier refills are available separately in a variety of layouts, including dotted, planner, and ruled.
