1 box protectors for Super Mario Cereal as pictured.  This may also fit others but please check your size first.   The actual cereal box that fits in these is roughly 10 7/8 x 7 3/4 x 1 3/4 or 27.6 x 19.7 x 4.4cm.

Do your research but some people suggest removing the cereal before storing.  We aren't experts on long term cereal storage so what you do with yours is up to you.  We just wanted to provide protection for the box for collectors since we had so many people ask about these.
