Vintage yellow shell beads

Is summer your season? These are your beads. These cheerful yellow scallop shells were made from glass in Czechoslovakia in the 1980s. They were made in molds. They are very well done with no mold marks. They are straight up bright yellow. There are slight indentations to mark the ribbing traditional on a scallop shell. Some beads are drilled across the narrow end of the scallop so that they hang fan side down; they are 14 mm long and 6 mm from hole to hole. Others are top-drilled. All are 5 mm thick and 14 mm across the widest part of the scallop. Price is for 10 beads.
