Longneck | SquarePegToys viking one end is 10 mmLongneck Smooth Depth Trainer THE tool for depth training. Gentle tapers and angled tips help make this toy more enjoyable. The wide heel near the top is large enough to simulate depth play with a hand but not so much as to add another unnecessary layer of risk.
