Yes, you need to know trustworthy shops with a good customer base and ones that are reguarded superior in piercing and tattoos. Thats the only shops I deal with because I dont want my product just in any shop. If you want to make plugs go for it, just please,please, PLEASE be sure to do extensive research on the woods you use, not just their common names but the latin names ie: dalbergia retusa. Also know which woods contain what quinones. Its worth it to yourself and your consumer so you dont give them a reaction to a certain oil from a species of wood. Im also glad to see so many open minded individuals in this forum. I do have to comment to those of you that called this a 'fad'. This has been done for longer than america has even been a country if you want it put into perspective. Its only surfaced in the western world in the last 20 years but has been done for hundreds of years in Asia,India,New Zeland,Borneo,Africa, Burma,.... the list goes on and on. Thanks to everyone who responded!
