What are the containers not intended for?

Certain Types of Beverages: Our bottles are designed for cold beverages only. Using them for hot, carbonated or alcoholic beverages may cause pressure buildup and is not recommended.

Unpackaged Food: We do not recommend using Stakki containers for non-packaged food. As the food is likely to cause build-up and affect how well the containers can screw onto one another. We recommend only storing prepackaged snacks in the containers. Or use a ziplock bag as a barrier.

Are there any safety concerns for my STAKKI?

At STAKKI, we are committed to providing safe, high-quality products and complete transparency to our customers. Our vacuum-insulated bottles are manufactured using industry-standard methods. The same method the vast majority of water bottles on the market use to ensure durability and optimal temperature retention.

Concerns may occur due to the nature of the sealing process for vacuum insulation. As solder/palettes are required to form a seal. Trace amounts of lead could be detected, even though we use what’s considered a ‘lead-free’ solder. Due to this, we use specialised machinery to apply a welded stainless steel cap at the base of the bottle for our customer’s added protection. Exposure should not be a problem under normal use.

While it is highly unlikely, if the stainless steel cap becomes detached for any reason discontinue use immediately. If the cap comes off during ordinary use, the product may be eligible under our Manufactures Warranty see Returns Policy
