The Bulk is a yo-yo released in 2014 by B.W.W.


Like the previous Wwing, the Bulk is a delrin offstring yo-yo manufactured to high standards for competition use. However, it also has a distinctively wide H-profile that makes it easier for the user to hit whips and orbits. The yo-yo is weighted to its physical size, but it is not too big as to tire the user out. It also comes included with thin O-rings and spacers, that allow for an adjustable string gap when installed on the yo-yo. The default configuration has proven best for open whips and regenerations with a smooth feeling when the yo-yo lands on the string and returns to the user's hand. The Bulk comes equipped with a large C-bearing and 19.6mm-sized silicone response pads.

It was at the 2014 World Yo-Yo Contest in Prague that Tsubasa Onishi himself had used the prototype model of the Bulk for his routine in the 4A Division. He had also used the Bulk at the finals of the 2015 North Japan Yo-Yo Contest in the 4A Division.
