Like all things on a guitar, things get scratched and wore down over time, this is especially true of pickguards and anything plastic. These rings from Musiclilly are a really nice swap out for the plastic trim that comes on most pickups. They lined up to be a perfect fit for my Epiphone, and it'll be nice saying goodbye to the scratched up pieces and replacing them with something new and shiny once I get around to swapping the strings. These also have a nice weight to them so the chance of cracks are almost non-existent.
