Lovevery “The Thinker” play kit 11-12 months. Received as a gift but forgot about it and never used it. My toddler took the blue balls and little bag when I was photographing the box to sell. Will try to find them, but it’s a bit of a mystery where she hid them. But otherwise everything is in great condition and ready for play time. Update: bag has been found…still looking for the balls. Willing to consider selling items individually. Just ask if there is something you are interested in.
