Just curious if anyone has any creative ideas for differentiating, labeling, or packaging the NaCl 3% vs 7% inhalation pillows? The percentage is not the easiest to identify, for the 3% or 7%. Labeling with the barcode already seems to be challenging due to the shape/size.

Attached is a picture of what we currently do, but just wondering what others are doing to compare and see if something else will work better.
