On Etsy since 2013

Cognitive Surplus makes designer science gifts using sustainable materials.

My husband, Geoff and I set out to create a stationery and lifestyle brand to celebrate the intersection of our passions – his for design, and mine for STEM, ultimately building Cognitive Surplus: Science Meets Design. We began making beautiful, science-inspired goods with environmental and social sustainability among our core tenants. We have won awards for both our green practices and our inclusive workplace where 50% of the people we employ have a disability.

Our DNA:
We know that it’s your hard work and strokes of genius that push humanity forward, and we build the tools to fuel your brightest ideas.

We appreciate that it isn't always glamorous and that breakthroughs are a lot harder than in the movies. We know how it feels to basically never feel like a superhero, especially when it seems like the answers are anywhere but in your data. We also know that for every failed experiment, late-night, and cold cup of coffee, you're helping light the way toward progress, and it's because of you that each day is a little brighter than the day before.

We make stationery and lifestyle goods to inspire you in your work and all along your journey, so you can find answers to important questions, and solutions to complex problems.

Custom and personalized orders

Most of our items are made in large batches, so we are not able to accommodate most custom requests, although if you are looking to order more than 50 t-shirts or tote bags, we can sometimes add a company logo to the exiting design - please be in touch for more details.

Wholesale availability

If you have a retail shop and are interested in wholesale, you can find our linesheet on Etsy Wholesale or on our website. If you have any questions, please email us at!

When will I get my order?

Orders shipping to the USA typically take 1-3 days to be processed and shipped out from our warehouse and then shipping times vary between 1-7 days depending on how far your package is going.

Orders shipping internationally typically take anywhere from 1-3 weeks to arrive depending on how long it takes to process through customs. If you think your order should have arrived but it hasn't, please check with your local post office as sometimes packages are held there if VAT taxes are due. Any taxes due at the time your order arrives are your responsibility. Please do your research before ordering so you are not surprised.

Do you ship overseas and how long will it take?

We ship to all countries! When you get to checkout, Etsy will calculate the cost of shipping your package to your address. Shipping times vary based on the country and shipping method.

First Class International: 7 days to a month+
• No tracking info after package departs the USA

Priority Mail International: 6-10 days
• Tracking number is valid all the way to your door

If your country charges VAT taxes, those fees are your responsibility. Please make sure to check your local tax rate on imported goods so you're not surprised when your order arrives.

We are not responsible for delays or for packages that go missing once they depart this country.

How much does shipping cost? (And how can I get free shipping?)

Shipping costs depend on the destination and weight of your order. Rates are calculated at checkout, so go ahead and put the items you'd like in your cart and input your address to see how much it will cost. Orders over $75 that are shipping within the USA qualify for free shipping if you use the coupon code 'dividebyzero' at checkout.

Could I get a different kind of paper in my notebook?

Please refer to our Learn Beautifully page here: to see what paper types are available for which cover designs. At this time we aren't able to offer customization requests for the inner page style, but if there's something you're burning to have, please let us know so we can keep it in mind for future development!

Can I get faster shipping overseas?

We can ship your order via DHL, which takes 2-3 days to pretty much any country. For most countries, this method usually costs just a few dollars more than Priority Mail International. Etsy doesn't have a calculated DHL shipping options, so if you're interested in this shipping method, please check out with Priority Mail International and leave a note in the notes field that you'd like a quote for DHL. If the shipping is pretty close, we'll upgrade you for free. If it's a lot more expensive, you can decide if you'd like to pay the additional or not. DHL is the most secure and guaranteed way to get your package. If anything goes wrong, you're covered.

Is there a cheaper international shipping option?

Unfortunately, we do not set the prices for the postal service (we wish we did!) Shipping costs are calculated by weight at checkout to automatically provide you with First Class and Priority Mail International pricing options at checkout. First Class International is the cheapest option we have at our disposal.
