I love these cobalt blue knobs so I decided to purchase more. My first purchase was to use them on my white Pottery Barn stand alone bathroom cabinet for a color pop. Now, I have decided to replace my silver hardware in the entire bathroom and add these beauties. I am ecstatic about these knobs. The quality is superb and the glass colbalt blue is a real eye-catcher. The shipping can be a bit slow, but the product is definitely worth the wait!
