Hydrating serum
This product is not as hydrating as it claims for my 56 year old skin. I have to reapply several times a day. There's no irritation or stickiness which is great tho.

Bookshelf bust
Color: White, Size: Small
This was smaller than I expected, I knew it was 6” but still just thought it would be a little large. But! It looks great on my bookshelf! Well packaged and looks just like the pictures
