With this box-tensioner your little one has something nice to look at.
Each tensioner is equipped with 2 bells and 2 wooden rings in different sizes.
As soon as your little one gets bigger, it's nice that he / she can kick the feet against the spanner. The rings and the bubbles will give a nice sound.
The tensioner can be attached to each box along the edge or over the entire length of the box.
Note: always check the tensioner for use in connection with the loose parts and that the tensioner is securely fastened.
If your little one is a little bigger, attach the tensioner along the edge of the box.
