Picks are essential tools for musicians who play stringed instruments such as guitar, mandolin, or bass. Due to their small size, they tend to be easily lost or difficult to find when needed. Current storage solutions for picks often involve bulky containers or special bags that are not always convenient to carry and often do not allow quick access to the picks. The technical problem addressed by the present invention is therefore to develop a holder that is compact and easily accessible for securely storing picks and keeping them within easy reach of the musician. The present invention relates to a plectrum holder specifically designed to securely and readily attach plectrums to metallic and magnetic surfaces, particularly mobile devices such as smartphones. The holder is characterized by a compact and flat design, which facilitates carrying. The magnetic attachment is achieved by integrated magnets (5) in combination with elastomer feet (4), which provide additional holding force through increased friction. Slotted recesses (7) in the base body (1) allow plectrums (3) of varying thicknesses and shapes to be inserted. The elastomer inserts (2) create a shoulder (15) that securely fixes the plectrum (3) between the clamping point of the base body (11) and the clamping point of the elastomer insert (10). The flexibility of the elastomer inserts (2) allows for a reliable range of plectrum thicknesses. This innovative solution makes it easier for musicians to always have their picks at hand without losing them, and represents a practical alternative to existing storage methods.
