Most frequent questions and answers
All four parts of unda are made out of 100 % Polypropylene (PP). Only the small seal on the big opening is made out of silicon. We choose PP because of its durability to different temperatures of your drink! Therefore unda can replace your single-use coffee/tea on-the-go cup. Preventing waste as well as production according to eco-design principles are part of the solution to stop the pollution of our planet.
It is 100% BPA- and BPS-free and complies with European (EMA) and US (FDA) laws. The unda is food grade, that means it is non-toxic and can come into contact with food.
We want the unda to be the last bottle you have to purchase, so we would encourage customers to give the unda a second life by repurposing it; it could be used as a cup (which should last a lifetime!) or possibly as a vase or storage for nuts or dry pasta. However, if you absolutely must replace it after years and years of daily use, it is 100% recyclable.

The unda breaks down into four parts, making it easy to clean by hand. It doesn’t require any extra cleaning supplies or soaps, just your normal sponge or cleaning brush. Plus, it is completely safe to wash in the dishwasher! We recommend cleaning your unda after drinking all non-water beverages.

Yes, all components of unda are dishwasher safe. For best results, we recommend placing the lids on the top rack.
Yes! The unda fits in standard bicycle bottle holders.
We do not recommend putting the unda in the microwave, as high temperatures occur, which could damage the shape of the bottle.
The unda isn’t a thermos, so your drinks will stay hot (or cold) as they would under normal conditions. Also, there is some heat transfer when hot drinks are in the unda, so we advise customers to take extra care when handling hot drinks. Also, your unda would love to be cleaned after your tea or coffee.
Yes sure, we do want that you can use the product as long as possible. Just reach out to contact@meerflasche.de to make arrangements for getting a replacement.
For now we only deliver to European countries. But we plan to expand also to other markets.

The storage base could be used as a second cup for room temperature or cold drinks, if you want to share your drink with a friend. Give it a quick rinse before re-attaching it to the bottle. Do not put hot liquids in the storage base and do not store liquids in the storage base when you are screwing it back onto the unda bottle.

The unda is only available in one color for all parts of the bottle. However, if you buy more than one bottle, feel free to combine the colors as you like. They fit together very well.

We’ve included a handy video on our main page to show the process. When the unda is a bottle (“bottle form”), the lid is screwed on the top of the bottle and the base is screwed on the bottom. See, it looks like a water bottle! To transform your unda into a cup (“cup form”), unscrew the lid and unscrew the storage base. Then, place the lid (with cap) inside the storage base and screw the storage base onto the bottom of unda. Voila! Your unda is now a tall cup with a wide mouth and no spare pieces.

The four parts are: the cup, the storage base, the lid and the cap. The liquid goes in the cup. The storage base screws onto the bottom of the cup. The lid screws onto the top of the cup (in “bottle form”). The cap screws onto the lid.

1. Bottle – When the unda is in bottle form (with the lid attached to the top of the bottle), it is the perfect lightweight bottle when you’re on the go and need the security of a leakproof lid and narrow drinking spout.
2. Cup – Alternatively, you can unscrew the lid and put it into the storage base, turning it into a large cup; now you’ve got a 550 ml (18.6 fluid ounces) cup with a wide mouth for easy drinking at your desk.
3. Storage base – Since there are no loose parts, there’s no worry about the lid rolling off your desk or getting lost under a stack of papers or getting lost in your bag!

We do not recommend putting the unda in the microwave, as high temperatures occur, which could damage the shape of the bottle.
