Two bottles, two feelings! Expand the social emotional learning of our original Express Your Feelings Sensory Bottles with the new opposites bottles. Add the Calm and Overwhelmed bottles to our other sets which are sold separately. Each bottle has a unique facial expression and colour, and the motion of its contents represent that feeling. The bottles can be used to help children communicate their feelings, or to self-manage their emotions. They are securely sealed and sized for little hands, which makes them ideal for use at home, in the classroom, in a calming corner, and on the go.
