Large enough to hold your piece? Check. Padded enough to protect said piece? Also check. Smell-proof so no one can tell how long it has been since you last cleaned your piece? Check again! Convenient handles so you look like an important businessman when carrying the bag? Check #4! A combo lock so you can keep people from snooping in your bag? Once again that's a check. Please note, we do not sell any TSA approved keys with this bag.
