FAQ

What is Stem & Cap?

A premium apparel and art print house built around psychedelic mushrooms and the mind. Wearable art that treats the subject with reverence, with a fixed share of every sale funding psychedelic therapy research.

Do you sell mushrooms or psychedelics?

No. We sell art and clothing, and our writing is educational. Nothing we sell is a drug or a controlled substance. See our note on products & content.

How are your products made?

Made to order. When you buy, your design is printed on demand by our print partner and shipped to you, so we hold no stock and waste less. Each piece carries a real idea, often a real scientific finding.

How long will my order take?

Allow 1–3 days production plus delivery — roughly 2–5 business days in the UK, a little longer abroad. Full detail on the Shipping page.

What's your returns policy?

Faulty or wrong items are replaced or refunded free, just send a photo within 30 days. Because everything is made to order, please choose carefully. Full detail on our Returns & Refunds page.

How do I choose a size?

Each product page has a size guide — please check it before buying, since items are printed to order. If a tee doesn't fit, we'll happily remake it in the right size.

Where does the give-back go?

10% of every sale funds psychedelic therapy research.

Are your products sustainable?

Printing locally and on demand cuts freight, carbon and waste, and we offer organic-cotton options. We try to be honest about this rather than overstate it.

Wholesale, press or collaborations?
