For anyone wanting to try the Personna Lab Blues, I found some locally. I live in Oklahoma City and went into Sally Beauty Supply (a National chain), with the wife, and took a look at the de blades they had in stock. I saw tucks of Derby Orange and I saw a package labeled Personna. Upon further inspection, I saw they were Comfort Coated and Made in the USA. I would say these are Lab Blues in a 5 blade dispenser. They were $2.99, overpriced, but is ok for someone wanting to try a Lab Blue blade without buying a larger quantity. Thought this might be of interest.
