Equations + Calculations Mystery Pack
You're here because you love the elegance of the mathematical world. For you, math is the explanation for everything, and you love solving problems with elegant proofs.
This Mystery Field Pack will surprise you with a collection of Cognitive Surplus goods that are all inspired by mathematics – everything in the shop is fair game! You could get notebooks, pencil cases, bags, glassware, stationery and more.
These packs are a great deal because you'll get items totaling more than $150, but you only pay $99.95!
Let us take care of the gifting for you! These packs are carefully curated with a particular theme or field of study in mind and they're a great way to treat yourself or surprise a loved one. You won't know what's in your box until it arrives, but it could be a mix of any products we make!
Limited Edition Field Boxes won't contain products that overlap with other Limited Edition boxes, but there may be some overlap with the standard mystery boxes. Items in the small and large edition of each mystery box will have overlapping products, and if you order two of the same mystery box, they will be identical.
Mystery Boxes can't be returned, but if something isn't right with your order, please reach out to our customer service team and let us know.
