mandolinlike
The term "mandolinlike" describes something that resembles a mandolin, a stringed musical instrument. Typically, a mandolin has a small, teardrop-shaped body, a fretted neck, and a soundhole. Mandolinlike objects would share some of these characteristics, such as a compact size, a curved or rounded profile, and perhaps a resonating chamber.
When referring to musical instruments, mandolinlike can indicate a shape or playing style that evokes the mandolin
