This campaign has ended.

KOTOBUKIYA US Online is turning one!

To thank all our customers who have joined us this year, we are holding our first Kotobukiya Plastic Mystery Box campaign!

What is the Mystery Box?

The Kotobukiya Mystery Box is a fixed‑price package that includes a curated assortment of Kotobukiya plastic model items.

The exciting part? You won’t know what’s inside until you open it!

Each box is filled with a unique selection of items, making every purchase a surprise experience.

Mar 17, 2026 (Tue) 12:00 a.m – Apr 15, 2026 (Wed) 11:59 p.m.(ET) or until the supplies last.

Scheduled to be shipped in May 2026
