Prothlink

Prothlink (often styled as PROTHLINK Co., Ltd) is a Japanese design and sculpting studio that collaborates with Kotobukiya on various plastic model kit lines. It is not an individual artist but a design firm that provides mechanical design and sculpting services for model components, especially in series like Frame Arms, Hexa Gear, and Frame Arms Girl.

Prothlink has been credited for its work on kits such as EXTEND ARMS05:RE2 for Kagutsuchi-Kou and the 1/24 Hexa Gear V-THOR, where it contributed to the sculpting and mechanical layout. The studio often works alongside individual designers and sculptors like Yasunori Shimizu and Hachioto, reflecting its role as a professional support team for larger kit development projects.

Their responsibilities typically include engineering weapon units, mechanical extensions, and articulation systems that align with Kotobukiya’s modular 3 mm joint standard. Prothlink’s contributions help ensure that model kits are both visually appealing and functionally sound for assembly and posing.

In summary, Prothlink is a trusted design studio that plays a behind-the-scenes role in enhancing the technical and mechanical quality of Kotobukiya’s model kits.
