Jane-I think your question was about the size of the plastic case? As Pete said this is the size of all cases dispensed from the new machines. Someone posted a message some time back about taking red cloth dye and dyeing the case. He said it worked. Someone else may remember who did the posting. If you find out who did the dyeing, you should check with that person and see if there is any long term problems with the dyed cases. I do not know of any after market red cases for sale.
