I never heard of JDM Sticker Store on fb, but for you to recommend them i'm pretty sure they're great.

Believe it or not, we started on eBay doing wall decals (Oz Little Sticker Boy), but with my love for cars, I branched out on focusing JDM and vehicle graphics. We use top industrial Japanese Mimaki machines to computer cut our decals on ISO rated premium Avery vinyls.

No over cuts, and imperfections from cheap chinese cutters, and Avery has guarantee no fade/peel/discolouring through european testing. Hence that's what we use.
