Ah, so you've noticed a typo! Mayonnaise - the sauce, is written with double ‘n’! I know. This font was named after a Smashing Pumpkins song that I like very much.
Mayonaise is a bit of an ugly duckling. It is strange, open and messy, and might not be love at first sight. BUT, when you spend some time with Mayonaise and get to know her, you might actually fall in love. Just like that song I mentioned earlier.
Go on then, give it a try! At this price, you can't go wrong!
