Yes, all our products are BPA-free.

Our bottles are crafted from high-quality, 304 food-grade stainless steel internally.  The exterior of the bottle is made from 201 stainless steel, it’s then powder-coated for durability.

We currently have one bottle size that is 32oz or 946mls (nearly 1L)

STAKKI bottles are 10.5cm in diameter and 25.5cm in height. 

This bottle features a leak-proof lid.  This means you can throw your bottle in your bag or car for easy transport. If your lid leaks, this is because A) one of your bottle lids isn’t screwed on correctly B) The seal has dislodged during cleaning and needs to be pressed back into place C) your lid has been damaged. 

The bottle diameter is 10.5cm and therefore will not fit in most standard cup holders.  However, there are cup holder adapters on the market that fit the STAKKI bottle. We have the goal to release our own STAKKI cup holder adapter soon.  Please note this bottle features a leak-proof lid.  This means you can throw your bottle in your bag or car for easy transport.

The STAKKI lid has a strong magnetic ring and can hold the majority of smartphones. If you don’t have a magnetic phone case, we have provided a stick-on magnet that you can apply directly to your phone or phone case. For proper adhesion ensure the phone has a flat, clean surface. Press and hold the magnet down for 30 seconds.  

The base container will likely fit most car keys. We recommend you remove your keys from your key ring and only include your essential keys to save space. 

All AirPods will fit in the base container! Other brands with larger cases may not fit.

However, our containers will still be useful to store loose earbuds in between use. Just ensure they are fully charged.

The containers are designed to store your essentials. Such as car keys, house keys, AirPods, bank cards, portable chargers, prepackaged snacks, prepackaged protein powder sachets, lip balm, zinc, doggy poo bags, or even to pour water into for your pup. You can assemble your perfect Stakki. 

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.

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, please discontinue use immediately. If the cap comes off during ordinary use, the product may be eligible under our Manufactures Warranty see Returns Policy
