<p>The device has a flexible and unbreakable casing (4) for accommodating a retractable token (1), and a attachment unit e.g. press (2) and magnet, for immobilizing a shopping list (3), where the token swims in an eyelet (5), which allows a passage of a ring (6) used for connecting a key-ring (7) or a door gadget. A notch is provided to stretch the token of the casing, where the token is retractable by swiveling or withdrawal from top to bottom. A marking system is adapted on a flexible retractable element without a shell.</p> |
