How to use
For best results with insert cards
We recommend using a Bic ballpoint pen when writing the information on the insert card allowing at least 5 minutes for ink to dry before folding and inserting the card into the wristband.
How to do know which size ?
To be sure of the size you need, simply wrap a piece of string around your child’s wrist, make a note of where it meets and then measure it against a ruler.
