To those troubled by the high cost of broken Rising Valkyrie cores: We offer special plastic made of the same material, reportedly developed by a certain company. These reinforced cores exhibit even greater power than the original while also possessing flexibility, making them virtually unbreakable under normal use. You can play with peace of mind. They have a shape similar to the original but with higher performance, and we consider them the definitive version of the Rising Valkyrie core. Recommended not only for Rising Valkyries with broken cores, but also for those who want to preserve their original cores. A stopper related to core assembly is included. The hold part (red part) is not included. The third photo shows everything included in the product.
