Mulberry Alexa - how much does it weigh?

I have been buying the Mulberry mini bags and absolutely love the size. I think I need to get the bigger size now that my daughter is a toddler and needs some things but not enough for a diaper bag….

I want a bag that isn’t too heavy and has space for some coloring things, travel size wipes and such.

Anyways…in the description Mulberry says the Alexa is 1/2kg but I find it hard to believe that bag is ~1 lb. Any feedback on the actual weight, especially given my use case, would be greatly appreciated.
