These are the real deal!! These are antique buttons that were tossed in the ocean decades ago. All are nicely frosted. None of these are made from glass, but were too cool to not list.

The largest button measures 1.7cm across. US Dime for size reference in the third photo.

Your beach treasure will arrive with a gift card that tells the short story of sea glass and the name of the ocean where your piece was beachcombed.
