Hi. I just bought a gorgeous dark green miu miu bag in the sale. I dont even know the name of it actually. Its a smooth leather and it looks like pleating on either side. Its like a rectangle with top handles that have little gold studs on them. It zippers shut and it also has a long shoulder strap. I want this to stay in the best condition possible for as long as possible. Should I treat it with a protective leather spray? Condition it? I have never had such a nice bag before and dont know what to do!? HELP!thanks!
