Thank you for viewing. This is a Durangle Super Inner Chinese style blade. I have used it for about a year, and the top layer on the back side is slightly peeled off (please check the photos). However, it seems to work fine when using it with sponge rubber attached. TOP Gear Series "TOP GEAR" is a high-end model item developed for top players and players aiming for the top, using carefully selected materials and advanced technology. Hybrid racket with the best of wood and carbon By placing the carbon position closer to the center based on the Durangle, we have achieved a feel and ease of use similar to a wood racket. It is designed so that the power of the carbon is only exhibited when hitting hard, resonating to the core. - Brand: Yasaka - Model Name: Durangle Super Inner - Type: Offensive - Construction: 7-ply (5 wood + 2 carbon) Thank you for viewing.
