Simple button/pin with gold rim and simple safety-pin backing as detailing. Source files are in download, including both .spp (Substance Painter) and .pdf, to easily replace the flag with any motif. Under 500 polys, so very cheap and performant. Simply attach to your avatars wherever you need it, chest, wrists etc. Uses Standard Shader. By default it is mildly emissive, which can of course be disabled. Enjoy!
