These one-fingered and two-fingered gloves cover your little finger (and ring finger) and the side of your hand so that you can move your hand over your Wacom tablet without it sticking to the tablet, raising the overlay, or leaving smudges.
To work out which size you need, align your knuckles against a ruler to find the width of your hand, see the blue line in the photo on the right:
|XS (Extra Small) ||up to 67mm|
|S (Small) ||up to 77mm|
|M (Medium) ||up to 87mm|
|L (Large) ||up to 97mm|
|XL (Extra Large) ||up to 107mm|
