Thanks for posting the info Fred and I want to point out something valuable in the illustration you've provided. NOTE: The chips are in a FLIP!!!! I once recieved a bright orange hs fractional in one of these packers that picked up streaks of adhesive from the corrugations. Took some tedious effort to clean the chip properly. DO NOT ship the chip nekkid in these things...use a flip!

And I just gotta add, apologies Fred, I'm only ever gonna use bubble mailers to mail chips.
