Custom Creator Expert 롤러코스터 빌딩 벽돌 장난감 세트 4619개

I thoroughly enjoyed build this model. Although it took much longer than expected, I'm not a professional, and this was the biggest set I've ever assembled. The mechanics initially felt a bit clumsy, but after added lubricant, they became smooth and efficient. However, one track section kept becoming loose. I resolved the issue by adding a few extra bricks for support, and it worked perfectly. Overall, it's an great build.
