Vintage Set of 4+1 Clamshell Glass Bowls Scalloped and Textured

Set of 4 shell shaped glass bowls, with 1 matching bonus extra Beautifully textured on the outside, smooth on the inside Clear glass with a tinge of green tint Smooth scalloped edging all the way around Flat base for stability Unmarked Four of these bowls are in excellent condition with no chips or cracks, and no signs of wear. The fifth is in very good condition with a line that looks like a crack but can't be felt on either side of the bowl and therefore may just be a fault in the glass itself (see last pic - it's hard to photograph because it blends in so well with the texture of the bowl). This fifth bowl feels ever so slightly different in texture, not quite as smooth on the inside? It may have come from a separate set, or may just have a bit more wear than the others. At any rate, I've decided to add it as a bonus bowl since by all appearances it matches perfectly and any differences are slight and can't be seen but rather only felt. Due to the nature of the shaped and textured glass there may be minor discrepancies in the glass itself, small lines that look or feel like miniscule cracks but are not. These bowls are approximately 6.5-7" in diameter and 2.25" high. These are not thin, delicate bowls - the set weighs in at almost 5 pounds. Great value on a set of 5!
