there is a reason why company doesn't give up their identity before the confirmation on material because there is a very high competition between the company's to deal this material . . so if one discloses the identity there are several ppl who ll provoke the seller to cancel the deal . . by draining their minds by giving wrong thoughts abt the company,checker or the financer

but this is a genuine deal but priorly until or unless the paper works for the material wont get over . . holding a radio active material is illegal
