If you find that you need a bigger size then we do offer a bespoke service, making them suitable for teenagers too. All of our thumb guards are secured by Velcro around the wrist, are adjustable, and will, therefore fit all size wrists.

The Thumbsie® will fit either the left or right hand. Your child is going to be wearing the fabric thumb guard during the day as well as night time, so we highly recommend buying three for each thumb that they suck, so you always have enough to maintain good hygiene.
