This is JT's first bimetal model with an inner rim. Based on the shape of the outer-rimmed bimetal model “OBTUSE”, the specs were fine-tuned to be smaller, wider, and heavier to match the inner rim. The OBSCURE is a very effective yo-yo in situations where you need to perform a series of tricks, such as freestyle, and in situations where you need to develop your moves in time with the sound. Please enjoy the possibilities of the inner rim model proposed by JAPAN TECHNOLOGY. ※ JAPAN TECHNOLOGY inspects all products by our standards depending on the characteristics of each product. Please refrain from purchasing if you are concerned about blurring, uneven coloring, or small scratches. ＜Spec＞ Diameter：56.3 mm Width：47.2 mm Weight：64.9 g Axle：M4×8mm Bearing：C size Pad：Slim
