This highly detailed hourglass features creepy human skulls circling a medallion of Celtic knotwork art, creating bases on both the top and bottom. The dark black sands of time flow slowly through the clear glass conduit that joins the two sets of skulls. Each turn of the sand timer counts for approximately five minutes. This 5 3/4 inch tall, 2 3/4 inch diameter timepiece is forged from cast resin and is great for game night, time-outs, and counting turns for board games.
