Each glass can is made in our home studio. We use a high-quality heat transfer process that adheres specialty inks to each mug. This produces a permanent, long-lasting image that will not fade, peel or rub off, unlike vinyl or markers.

Soak the top in vinegar or an eco-friendly alternative of your choice. Let air dry. Please note: You must properly clean and care for your bamboo lid to avoid mold and mildew. I am not responsible, nor liable, for improper care.
