Every meaningful gift starts with a connection. Founded in 2025 (operating under 21ST MERCH, LLC), CustoJoy began with a simple passion: helping people celebrate the most important things in life—their families and their pets.
We are a tight-knit team of designers working out of our office in Westminster, California. Because our focus is entirely on creating unique, made-to-order personalized apparel, we operate strictly as an online design studio. We don’t have a physical showroom or offer local pickup. Instead, we pour our energy into the creative process and partner with reputable print facilities across the US to professionally bring our designs to life and ship them directly to your door.
For us, delivering joy goes beyond the product itself. That is why we are committed to providing clear product information, transparent store policies, and responsive, human customer support every step of the way.
