How to take care of an expensive bag

Recently I bought my first expensive leather handbag. It's something that I've wanted for a while, finally I felt like it was the time to splurge. It's a Furla Like S in Onix. I spent a lot of money on this bag. And I want to give it the best care possible. I've done some research to see how I can ensure this handbag will last me a long time, and always look good. 

Here go some general tips.

The first tip is really basic: Be extra careful! Not that I'm not careful with my other handbags, but just try to avoid careless mistakes! To be more specific: 

1. Avoid handling your bag if your hands are dirty or if you have lotion on them.

2. Avoid squishing your bag or stuffing it with too much stuff, avoiding stretching it out. 

3. Avoid -- at any cost -- getting your bag wet. Apply regularly an water-repellent spray.

3. Keep your bag out of direct sunlight, or heat sources.

4. Rotate which handbag you carry regularly so that they don’t wear out too quickly.

5. Use a suede brush to clean and revive suede.

6. Regular use of a leather moisturizer will keep the leather supple and free of cracks.

7. Wipe your bag down on a weekly basis (when in use) with a soft cloth.

Keep the inside gunk free: Use pouches to store cosmetics and liquids, which will protect the handbag lining from spills. Avoid click pens at all cost, go for pens with caps instead. Better yet, put those in your pouch too, in case of dreaded ink leaks. And candy! Don't put candy in your bag. Just don't. 

Store them properly: up right position inside the cotton dust bag they normally come in. Good substitute: cotton pillow case. Never, NEVER, store them in plastic bags, because it this traps moisture. Cross the handles over each other to avoid wear on the bag and unclip any removable straps. If the bag needs something to keep it's shape up, stuff it with scarfs, or a t-shirt, or acid-free tissue paper -- it's really inexpensive on eBay, and you can keep using it over and over. I asked for some in the store where I bought my handbag and they were super kind and gave me enough to stuff my bag.

Products that were recommended to me:
- BÚFALO Leather Protection Spay. This spray nurtures and protects the leather and it can be used on anything that's made of leather around your house. It's cheap and It really helps keeping your bag smooth and beautiful. I got it a local supermarket.
- Waterproof spray for leathers. I've gone thought many cans of this -- from may different brands, I always get at my local supermarket... I apply it on shoes all the time too. It's perfect for suede!
- Magic Eraser (also known as melanine sponge). Bought a bunch of them off of eBay, really cheap. It's great for cleaning hardware and little decorations. Also works really good on shoes btw. You don't need any product, just a tiny but of water and it just makes everything shinny and lovely again.
