I love the quality and the color and the design I got to customize them to the way I like my husband and I are different and it was really nice that I could custom mama instead of mommy or mom because I like to be called mama so that was nice and then I was able to make his big sisters to buttons as well so that was really nice. I love the design it’s simple it’s cute I can’t wait to wear them on my baby shower day.
