What a beautiful kelly! I have a black box sellier, so I understand your hesitation, but the bag was created to be carried and loved. While it may acquire a scratch or scuff here or there, that is to be expected. The first one is the hardest, but over time, they attest to the life of the bag.
A decorator told me about some clients who never used their beautifully decorated living room. After years of being a room to view, not use, the client decided to enjoy the living room. Unfortunately, the springs in the upholstered furniture had become so stiff from lack of use that they were sprung, and the silk upholstery had dried to the point of splitting. The clients had been too cautious, and the pieces "died" from lack of use. Something similar happened to a car of mine, a convertible that I kept for special occasions. Those occasions were so infrequent that the car was rarely started. Someone pointed out to me that cars need to be driven- the gas, oil, fluids, etc. need to move through the various parts and hoses to keep them from drying out. I ended up spending quite a bit to flush the system and replace hoses, etc. all from lack of use. My car experience taught me a valuable lesson: cars, furniture, bags- they are all created with a purpose and that purpose is what gives them life. It is far better for your kelly to develop a scratch or two while being carried and loved, than to sit in a closet becoming stiff and dry, so my advice is to respect your beautiful kelly but let her serve her purpose. You will find that your kelly will become truly yours, and that will make her the best kelly of all!
