LICENSED BLS PATCH ....READ THIS I only sell licensed patches my patch shows license it is the correct thread and fill material. I have posted  the bootleg example on bls flag patch listing. I worked on a tour with Ozzy and Zakk in the early 1990's . Zakk is a good guy buy the licensed product from me You either care about BLS allow Zakk his family and band mates earn royalties or you can support the bootleggers who sell phony stuff. This patch is supposed to be silver white thread the bootleggers use cheap white thread. I have included a photo of the license on the back patch is 1.25 ish" x 6" inches long
