The Imbucare Box with Flip Lid–Knit Ball (SKU: I 320) pairs a single circular opening with a soft, tactilely engaging knit ball, making it an ideal early imbucare experience for infants around 8–12 months who are developing intentional release and object permanence. The flip lid's return mechanism provides immediate cause-and-effect feedback, sustaining the child's interest through repetition. Its soft ball is a thoughtful variation for children who are not yet ready for rigid wooden objects, and it integrates seamlessly into an infant-toddler shelf sequence.
