About this tube 
     The auction is for one tube .Frankly speaking,Shuguang Corporation doesn't have 274B matched because they think that products with the same batch will have similar data.We directly ship the tubes from Shuguang Corporation and we don't match them by ourselves.so they are not matched but the same batch.
