I know there are lots of posts on this, but I guess I just need some confirmation that I should treat the handle of my new LV Delightful pm with the "leather kit designed for LV bags" from Lovin My Bags before I use it to prevent water marks and stains. I haven't used my bag yet and I'm still waiting for the kit to arrive. I have a totally MM bag and never did anything to the leather but I'm also not loving that bag due to the leather tabs curling up. I just love this new bag and want it to last. Any thoughts would be greatly appreciated!
