What size do I need?
Fits Like a Glove

The thumb guard is worn like a glove, it fits over the thumb and is secured with Velcro around the wrist, so is easily adjustable. The guard will fit either thumb and will not limit the child’s ability to play or use their hands.


Outside: Union Jack 100% cotton fabric.

Inside: Thumbsie® branded cotton fine warp satin fabric.

We suggest washing by hand or in the washing machine at a low temperature.

Approved by professionals

We are delighted that Thumbsie® has been ‘Approved’ through the Oral Health Foundation Accreditation Scheme and that they recognise Thumbsie® as a useful aid in oral health.


Thumbsies® thumb guards are available in extra small, small, medium, large and extra large. Please use our size guide to get the best fit.
