Price of rp is calculatted by lab report.buyer says always for testing sample like camera reel, double sell plastic big torch, plastic watch . He does lab. If iridium percent remains positive then buyer will ask to you about rate. Actuly rate starts with nano gram.seller rate does not active here.seller have to prove that he has rice puller and it's original, so without sampling rp deal is only nightmare. Parmar 9039181937
