Lifestyles change as we journey through the years. A purse that you have prior to kids may be different than the purse you have when they are an infant and toddler. Even if one does not have kids there is the purse for work versus the purses you use once those years come to a close. Where I am going with this is to envision that would best suit your needs in all phases of life. If a purse is too large and/or heavy, does not suit your frame, then the choice is a no brainer.
I am similar to OP that box scares me so I traded mine. If you are unsure, let it rest, sleep on it and the answer will come. The worst would be to sell and have remorse later.
I agree with everything, however, I love box, even just to look at.
It's difficult for me to part with my things so like your thoughts, it's best to wait till/if you are ready
