As with all our t-shirts and other products, if you’re not completely happy, we have a no quibble returns policy. However, if you do like your new mug, why not tag us on social media in a photo of you using it? We love to see people enjoying a drink from these.

If you share a photo we’ll even send you a little discount code as a thank you!  If we’ve missed it, just drop us an email by replying to your order notification. Or get in touch using our contact page if it was given to you (or if you snuck into our facility at night and stole it).
