Fender strap blocks. I bought these in bulk as spares for my guitars and basses, but I won't be using them for a while, so I'm selling them to organize my things. All are new and unopened, and this is a set of 4 packs (16 pieces total). Each pack contains "2 black and 2 red" pieces, so there are 8 black and 8 red pieces in total. You simply put them over the strap pins, and you won't have to worry about your strap coming off while playing, which is very useful. If you have a lot of instruments, or if you want to stock up on spares, how about it? ● Condition: New, unopened ● Shipping: Mercari shipping (anonymous delivery, shipping included) Instant purchase is OK. I've made it cheaper with the bulk purchase, so I would appreciate it if you could refrain from buying individual pieces. Thank you! #Fender #Fender #StrapBlock #StrapRubber #GuitarStrap #Guitar #Bass #ElectricGuitar #ElectricBass #InstrumentAccessories
