Tote Bag

I love my bag! It’s made with canvas, my favorite fabric. The seams are sturdy, double sided and it has an inside pocket. I’ve gotten many compliments on it.

Perfect Gift

I gave this gift to a friend who is a math teacher. She absolutely loves it for carrying stuff back and forth to school. You can tell the tote was well made with good materials and fabric. The equations are printed nicely and very legible. Now I'm thinking of purchasing one for myself!

Thrilled geeks with a bit of style

We are really thankful to have found this brand. My wife is a former math teacher and loves her canvas bag. I have thoroughly enjoyed my constellation whiskey glasses and we have already forwarded the store link to friends who are excited about making some purchases.

Gift for math teacher colleague

My colleague loved this for a going away gift. I coupled it with one of CS's math-themed journals for jotting down ideas. Went over very well. The kinds of gifts l'd love for myself!
