Just over 3 twists.. 3.5 to be exact. Superb assembly and a really good one to look at in hand as the corking stands out with the clear in between. Many of thread just look dark in hand without proper front and back lighting One pin head size half moon seen under loupe with another micro sparkle crescent and a couple faint thin scratches. Everything else you see there are all asmades inclusions.. There's abput 4 of them that look like little dimples. The corking does twist into the center leaving the darker edges to the exterior Gorgeous collector piece!
