Sizing guide

This pale blue 2-ply polyester non-medical face mask, featuring a filter pocket on the inside, comes in two sizes (measurements below). The design on the front is of a cute pun on the word cation.

A cation is an ion with more protons than elections giving it an overall positive charge. A dication has a +2 positive charge and a trication a +3 positive charge (but they are both cations, they can just be given special names indicating how much extra positive charge they have). Here's some cats and balls of wool to illustrate it :)

The Small/Medium size (10.8cm x 16cm) is recommended for older children, and the Medium/Large size (13cm x 18.5cm) for adults.

Printed using the permanent dye sublimation method with inks that are water based, eco-friendly and vegan, OEKO-TEX® approved (they don't contain any regulated or unregulated chemicals harmful to the environment).
