If the Dbold you have is by TTokkyo they should be small about 1/16 thickness, it should have TT stamped on one side and scored down the middle on the other side. They are supposedly 10 mg. They are sold in lots of 1000, 500, 100. They may not come in a container as they are often bought in bulk and split up by local AS dealers. They should have cost you around $1.00 to $1.50.
