List of products by brand Jin Choi

Jin Choi was born and raised in South Korea. She earned a Master’s degree in architecture at Yale University, where she met her husband, Thomas. Together, they founded an architectural practice in Boston, with projects ranging from product design and architecture to infrastructure and public art installations. Jin first created Shapes at Play, then a handcrafted book, for their child when he was only a few months old. She wanted to “tickle his brain” with shapes that are related and transformed and demonstrate how to recognize them. With the inspiring giggles and contemplative long gazes she received from her son, Jin was encouraged to create more books for young children in the future. Visit her website at
