“Keyminder“ not only serves as secure packaging for new padlocks and keys, it also includes a tear-off label for spare keys. This paper-based blister packaging completely avoids plastic waste through its innovative cartonboard design. Once opened, “Keyminder“ allows you to label your unused spare keys with a tag that is part of the packaging and is already attached to the key ring. The label can be detached from the packaging and marked up as you open the packet.
