FAQ

How long will my order take?

Each shirt is printed to order. Production takes 2–5 business days, then standard US shipping takes 3–4 business days, so most orders arrive in about 5–9 business days. Holidays can add time.

Where do you ship?

Within the United States.

How much is shipping?

Shipping is calculated at checkout before you pay.

Can I return or exchange my shirt?

Because every shirt is made just for you, we can't accept returns or exchanges for a change of mind or the wrong size or color. Please check the size chart before ordering.

My shirt arrived damaged, misprinted, or it's the wrong item. What do I do?

Email chem@periodictees.com within 30 days of delivery with your order number and a clear photo. We'll send a free replacement or a refund. You don't need to send the item back.

My package never arrived.

If it's 3+ business days past the estimated delivery date, contact us (within 30 days of that date). We'll check with the carrier and replace or refund a confirmed lost package.

Can I cancel or change my order?

Yes, within 2 hours of placing it: email chem@periodictees.com for a full refund or change. After 2 hours your order is in production and can't be changed or cancelled.

I entered the wrong address.

Tell us right away — we can fix it before the order ships. If a package comes back as undeliverable, it's held for 30 days; we can reship it to a corrected address, but reshipping costs are the customer's responsibility.

Do I need to send an item back?

No. Please don't mail items back to us. Just email chem@periodictees.com with your order number and a photo, and we'll reprint or refund.

Can you make a word or name that isn't in the shop?

Try the speller. If your word spells with element symbols but isn't a product yet, use the "Request a custom design" link.

What are the shirts made of?
