Hydrogen Purr-oxide Science Cat Pun Face Mask

Sizing guide

This purple 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 molecule hydrogen peroxide, giving the atoms feline features! The hydrogen atoms are now small round white kittens and the oxygen atoms are larger ginger cats, in a kawaii cute style. Includes the text "H202 hydrogen purr-oxide". This design idea was given to us by a US chemistry teacher.

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