As a child of the 1980s-1990s, TMNT holds a special place in my heart. I have the entire original series on DVD (a little disappointed that it doesn’t hold up so well). I own the 3 original movies, and I still have most of my original TMNT toys from childhood. I’ve since bought numerous TMNT actions figures, shirts, and gotten into the comic books. So, this piece was a long time coming. The design is fairly simple. The bulk of the cost was in the backing, and having to place multiple orders across sellers because I couldn’t consolidate the parts list better. And, the part for the “knot” in Donatello’s bandana was only available in 2 sets, according to Brick Set.
