LEGO Level Four - Kit 12, Inventor's Lab (20211) was released in 2012 as part of the Master Builder Academy theme, with 208 pieces and 1 minifigure. That makes it the 9th largest of the 14 Master Builder Academy sets in the catalog. It was one of 9 Master Builder Academy sets released that year (see them all). Released in 2012, 14 years ago, well past the two-to-three-year run most LEGO sets get, so it is almost certainly out of production.
