The Plectrum Box is a nice looking heavy wood (maple or rosewood) box, the shape of a plectrum and the size of an outstretched hand. Inside, it's lined with velvet like a jewellery box, with room for plectrums, slides, capos and, well, anything else that a guitarist might want to keep safe in a small box. They're not cheap - £50 for black, £65 for the nicer wood finishes - but they're a pretty good gift for an impossible-to-buy-for guitarist.
