The Acelash, released in 2013, is Bandai's Hyper Yo-Yo version of YoYoFactory's very popular looping model Loop1080. Both yo-yos differ only in model name and side cap graphics. (The Loop1080 was discontinued in 2017 and replaced in 2018 by the Loop2020). Both models use YoYoFactory's key system that lets you adjust the string gap easily and quickly.
The Acelash was released only for a very short time in Japan and is now (2020) quite hard to find.
Uses a size K ball bearing axle and starburst response.
