I was looking for some STEM puzzles for an older child and i am lucky to have found The Playroom! Quality puzzle pieces and top notch customer service - ask them anything! They respond quickly and the orders are processed and delivered fast as well. We like that they are parents too, hence they know what parents are typically in search of. Their Let's Guess and Robot Animation brought us many hours of fun and laughter, playing and bonding as a family! I highly recommend them to all my parent friends!
