FiDLBiTZ 스타터 세트

My nephew spent an entire afternoon connecting these little cubes into a castle, and the best part is they actually stay put without any sticky residue on his fingers. I was surprised how solid the structures feel despite each cube only being a centimeter.

I bought these hoping they'd be a fun fidget or building toy, but the cubes don't hold together as firmly as I expected. They stick okay for a simple tower, but anything with weight just collapses.
