These are very pretty knobs, at a great price.  The bubbles in the glass remind me of the shallow edge of the surf on the beach.  I bought the clear to use on my white kitchen cabinets and they certainly add a touch of elegance. There was two damaged knobs in the box, but Wayfair customer service was fantastic to work with and I had an entire new box of 12 knobs to finish my project.  I in no way attribute the broken knobs to the quality of the product and would not hesitate to buy more of these knobs.  I have nothing but praise for the quality of the product and Wayfair's excellent customer service.
