Demon Slayer Tsugikuni Yoriichi Katana Building Set - 606 Pcs Anime Toy Blocks Compatible with Lego | Perfect Gift for Anime Fans & Collectors | Great for Role Play, Display, and Creative Building

My 7-year old son assembled it no prob. No missing pieces. Durable enough to handle, but the blade does slowly come apart as its gently swung around. Easy enough though to compress the pieces back together before it falls apart. Overall a great building block set, especially for the money and the fact that Lego does not make anything like this.
