The T1 is a collaboration between One Drop and Toxic Strings. It was made to benefit Trevan Evans, son of Evan and Angie Evans who own Toxic Strings. Evan was diagnosed with Type 1 Diabetes and a percentage of the proceeds from each T1 goes to help Evan's medical expenses.
The T1 is a large yo-yo with a unique ridged catch zone, larger than the grooves on other One Drop yo-yos like the Project. It uses a tapped axle, Flow Groove response and a 10-ball bearing and is finished in One Drop's signature Pyramatte.
