Offiper Cups

Yes, the Offiper stainless steel tumblers are dishwasher safe. Their durable construction allows them to withstand regular cleaning cycles without compromising the integrity of the material.

The double-wall insulation is designed to prevent condensation on the outside when holding cold drinks and keeps the exterior comfortable to touch when filled with hot beverages. While they provide good temperature retention, they are not vacuum-sealed, so they will not keep drinks at extreme temperatures for as long as a dedicated thermal travel mug.

No, this set of four tumblers does not include lids. They are designed as open-top cups, making them best suited for casual use at home, camping, or outdoor gatherings.

High-quality stainless steel is non-reactive and food-grade, meaning it should not impart any metallic flavor to your beverages. They are a clean, neutral option for water, coffee, or juice.

The stackable design is quite efficient, allowing you to nest all four cups together. When stacked, the set stands only slightly taller than a single cup, making them easy to tuck into a kitchen cabinet or a camping gear bag.
