This plastic-free packaging solution for S-Locks, which are used to secure guitar straps, is characterised by sustainability and functionality. The packaging consists of a box made of solid cardboard and a biodegradable tray made of reinpapier® in which the guitar accessories are securely held in place. reinpapier® is not only biodegradable, but also sturdy enough to optimally protect the S-Locks. The design and printing of the outer packaging is simple but appealing. This design minimizes the ecological footprint without compromising on quality and protection of the products.
