The Imbucare Box with Woolen Ball (SKU: I 060-1) is among the earliest imbucare materials in the infant-toddler sequence, appropriate for children around 6–8 months who are beginning to develop intentional release. The soft woolen ball accommodates the palmar grasp still common at this age, while the circular opening in the box introduces the concept of object permanence as the ball disappears and can be retrieved. Its gentle texture and manageable weight make it an appropriate first posting experience before transitioning children to rigid wooden objects.
