Here's your chance! This amazing set of Russian Seraphinite Concaves are being sold at highly discounted price because of a small flaw. From a side view you will notice a slight tapering of the thickness. It tapers from a >1/2" OAL at the thickest to >7/16" OAL at the thinnest.
This oversight is quite minimal and could actually work out as a good thing for anyone with lobes that are thicker around the bottom than the top (common in people with cut lobes)
