They are looking for endangered animal products, purses by well known design houses are not typically on that radar. However, as a precaution, it is best if travelling with an exotic to have the CITES (or a copy) with you. Shipping is another issue, I would not risk purchasing or shipping without the CITES no matter the brand. Spa should not be a concern as Hermes will do the shipping themselves (if it is needed).
In general, I would be more concerned about the duties/tax that can be imposed at will by any border officer when returning from travel. If you can't prove you had the item when you left your country, they can seize and fine. There are ways to have your expensive items documented by the border services, which is very handy if you don't have receipts. (IMO it is ridiculous to have to carry that proof but they have the right to question all items entering the country, especially since so many people "forget" expensive items off their declarations) In a pinch, I just take a picture at the airport before departing to date stamp - no guarantees, but at least it is something that is difficult to refute.
