Are the two boxes of blades below the exact same blades just in different packaging? Both say comfort coated, but one say it with yellow highlights around the wording and different packaging design. Also, are these Personna blades called “lab blue”? If so, are they different than the medical prep Personnas in regards to smoothness and sharpness? If anyone has used the blades below what are your thoughts on them? I purchased a 5 pack of Personna comfort coated blades from Duluth Trading Company and found them to be quite sharp and snooth. Pictures below. Thanks, Mullard
