About the Seiji
The Seiji is Park Junsang’s first signature throw for UNPRLD, released in 2022. Constructed from a 7068 aluminum alloy body — a high-strength alloy less common in production throws — with stainless steel rim weights, the Seiji is one of the few UNPRLD models to use 7068 as its body material. Junsang’s second UNPRLD signature, the Tenacity, followed in 2025.
