Product Description:

Cast Oskar, first released in 1987 and highly popular among puzzle collectors, has now been revived as “Cast Key III” with new gimmicks added. At first glance, it appears to be a flat puzzle where three keys are to be pulled out from the case… Designed by Oskar van Deventer from the Netherlands.

Challenge: Pull out three keys from the frame. Each key has a different shape of protrusions, requiring not only pulling out in the correct direction but also sometimes putting them back.
