Flanger FT-12C Clip-on Tuner (New button battery just installed) Shark-shaped Capo Picks: 3 This is a set of 3 items. My daughter used these for a short time in her light music club, and they have been stored at home for a while. The capo has some rust. Would these be suitable for someone starting to play the guitar? Please understand that these are used items. *Shipping will be via "Yu-Yu Mercari Delivery," but may be changed to "Raku-Raku Mercari Delivery." Please be aware of this.
