The Mystery Box is a five-sided box measuring 34 cm x 30 cm x 19 cm. The front has two holes to which fabric sleeves are attached, allowing students to insert their hands and identify the objects inside using only their sense of touch. The back of the box is open to allow a teacher to observe or to add and remove the objects. The back also has a raised lip to keep items from falling out. The box can be placed on a table or on the floor with the open side down and the objects placed inside. This item can be used together with the items from the Stereognostic Bags in our Discount Montessori products line.
