Love a surprise combo curated just for you! We’ll hand pick the silicone pieces, which might be matching or a super cute mix of colours — past, present, or even unreleased. It’s total mystery, total fun... and totally final (no returns on Mystery Cups!). Our best-seller for a reason. Designed for effortless sipping, it holds up to 12oz of your favourite hot or cold drink and features our patented Reverse-Force™ Lid for a leak-free experience. The fully enclosed, non-slip base feels amazing in your hands. Made from lightweight borosilicate glass, it delivers a pure coffee taste and is super easy to clean. With its perfect blend of style, function, and comfort, it’s no wonder it’s a customer favourite year after year.
