Blenko Glass Small Blob Paperweight. The bottom is ground and polished, stamped Blenko 2015. This paperweight would have been sold in the Blenko gift shop, it's not a catalog item. It has swirls of blues and grays with many air bubbles. It's about 2 1/2 inches tall and about 2 inches wide. A cute little whimsy item. There are no chips or cracks.
