One of the most unique features of the Totobobo Mask is the “Cut to size†feature. The original mask fits most adults except users with smaller faces, for example, women and children.
What you need :
A clean pair of sharp scissors
A pair of clean hands
Firstly, you’ll have to determine how small you want the mask to be trimmed to. You can do a quick estimate by covering the mask over the user’s face, or better yet, get a Totobobo Simulator. If you’re uncertain of the exact size, we suggest you to trim the mask down a ring at a time. The mask should ultimately form a snug fit onto the face, but not too tight to hinder the comfort of the user.
Remember to measure twice before you cut.
Then, carefully cut the mask starting from the bottom ring. Follow the markings carefully and slowly cut through the mask. Trim any excess bits and test the size if necessary. The excess material that has been cut out can be disposed and the mask is ready for use.
