FAQ

What is Stem & Cap?

A premium apparel and fine-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 mental-health and psychedelic 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 partner Gelato 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). Changed your mind? UK & EU customers have 14 days to cancel. Full detail on the 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 and mental-health research. [Named research partner to confirm.]

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?

We'd love to hear from you — see the Contact page.
