Use the 3 Way Mask Clip with the Airbon Kids Mask for children ages 5 - 7. 
 
The 3 Way Mask Clip can also be used for children ages 10 - 12 who may prefer the Air QUEEN Nano Mask, depending on their face shape.  My son who is 10 prefers the Air Queen Nano Mask with the 3 Way Mask Clip.
 
The 3 Way mask Clip can also be used by older children and adults who may prefer a tighter fit.
