Proteca's large-capacity 100L suitcase, the maximum size allowed for checked baggage. I purchased it about 10 years ago and used it 4 or 5 times. There are signs of use on the exterior. I will sell it to someone who understands this. The casters and handle function without any problems. It has a caster lock. - Color: Purple - Lock function: Yes (Proteca) - Keys: Yes (with 2 keys) Thank you for looking. Carry case size: L (for 7 nights or more)
