I am very impressed with the quality of the products that Cognitive Surplus produces. The totes are no exception and there is something for everyone in the range of scientific disciplines. Very happy

Received quickly and loved the look and craftsmanship of this mug! Is a gift for a very special family member so I am thrilled to see his reaction! Thank you Cognitive Team- a job well done!

They were a perfect gift for my husband and my brother in law.

Teenage Granddaughter loved the new experience of using these *metallic markers (I also included a package of good black paper so she could experiment). Colors are beautiful and gift was a big hit.

Love the material. Great quality. Short runs long from the waist down depending on your height but great product.

Love this mug! Absolutely beautiful and just as described.

I got this for my animal scientist friend as a Christmas gift and she loved it.

The mug arrived very well cushioned and packed, and the images are so pretty! I love the weight in my hand (but it’s not oversized) and I anticipate the dark colored interior will hide the tea stains this will accumulate sitting on my desk

Needed gift for Principal Investigator of a lab, was very original and got everyone talking!

This is my absolute favorite mug - both for myself and to give as a gift. The texture; the colors, the shape and size. I've gifted it this year to my kids' teachers at a nature-based preschool.

I gave this mug away as an exchange gift. I'm sorry I didn't keep it for myself!

I've been lusting(?) after this tape for over a year. I first discovered Cognitive Surplus at the gift shop at Silver Falls, where I splurged on some gorgeous (prob my favorite of all) butterfly washi tape (and left the trees and honeybees behind), then got home from our vacation and looked you up online. My husband has had two open heart surgeries since we've been married (we're only in our 40s), so anatomical hearts have an extra special place in ours. I cannot wait to use this for Valentines Day in a couple of months. If I could own a lifetime supply of washi tape, it would all be from this store! Thanks for making awesome, beautifully rendered, educational stuff!!!

I accidentally forgot to remove this one from my cart when checking out (if money were no issue, I would own multiples of almost every tape on this site! It's very difficult to narrow to only a few---but at $6/each, it's necessary). When it arrived, however, I was thankful. It's very cute and I used it right away to decorate a gift for a white elephant sale. Funky and fun and well done.

Let my science-obsessed daughter choose some washi tapes to get us to free shipping, haha, but I still had to get myself some. : ) This is cute and will be fun to use on gifts for said daughter.

Beautiful
