Cool Maker Charm Bar Studio Kit. Design personalised accessories with the Cool Maker Charm Bar Studio. Choose a charm shape, fill it with decorative pieces and use the studio to seal a creation ready for display or wear. Colourful gems and mix-ins invite children to experiment with different looks, while the included bracelet and attachment pieces offer ways to show off the finished designs. The studio format also provides a place to organise the activity between creative sessions. Enjoy choosing a design, trying a different approach and making the activity your own during a relaxed creative play session.
