1. Fill your Bottle with warm or distilled water up to the line
2. Drop in as many tablets as required (one tablet for every 50 ml of water).
3. Wait a few hours --once the tablets are dissolved just start using the product! Shake it before each use afterwards.

The solution in our bottles should last you a similar length of time as a traditional skincare bottle, deodorant or shampoo. How long one bottle's worth of solution lasts depends on how often you use it, how much you use, and how many members of your family use it as well! If you need more help on identifying which products or refills you should purchase and how often, please provide more information and we'll do our very best to assist you!

Using warm water will best minimize how long you need to wait to have a tablet dissolve. Using cold or hot water is also okay, but we would recommend warm water.

You do not have to but you can. It will help dissolve the tablet in warm water faster.

Our bottle is forever refillable, it is meant to be used forever so you never have to throw it away. Unlike many conventional disposable skincare or soap bottles, our bottles are made of glass (for small and medium ones) and BPA-free (for the 450ml ones), made of shatter-resistant material, and contain no VOCs or phthalates.

One skincare tablet makes 50ml of solution.

For an easy and optimal experience we recommend you use our MONO bottles with our refill tablets as we specifically designed them for a great consumer experience, and specifically designed for reuse.

We don't want you to pay to ship water around the world and we do want to minimize our carbon footprint. You can add your own water when you receive your bottle or at your own convenience.

Each tablet is the made to be the perfect amount for your MONO refillable bottle. Each of our tablet creates 50ml of solution, so four tablets create 200ml and 8 tablets 400ml. If your bottle shows 50ml of product use only one tablet at a time.

It depends on how often you use it and how many people use it in your family. If you need more help on identifying which refill packs you should purchase, text or e-mail us.

You could but it is not recommended. Indeed you could use a different MONO bottle with a different tablet pack but the labels printed on the bottles are permanent so in case you do we suggest you re-label your bottle.
