We call these buttons our Metal Dome Picture Buttons. They all have acrylic domed tops. These buttons have the option of high or low domes. The high domes are 3/8" high and have a slight magnification. The low domes are 1/8". These domes are acrylic, so we recommend that the buttons be removed before washing, so the domes don't scratch.
Picture perfect domes in both high and low are available with most button styles. You an email us to ask about ordering a particular style in either high or low, and also in Antique Brass, Antique Silver or Gold Bezels. We mostly have Gold bezels on hand but can order in whatever you would like. Email us at firstname.lastname@example.org or call the shop at 360-357-3443.
