Discover what comes in the waterdrop 30 Days Starter Set Glass, how to use the glass bottle and Microdrink cubes, and tips for building a daily hydration routine.
Quick answer
The waterdrop 30 Days Starter Set Glass includes 60 Microdrink cubes in five flavors and a 20 fl oz borosilicate glass bottle. You drop one cube into water, wait for it to dissolve, and enjoy flavored hydration throughout the day.
Why choose the glass bottle version?
The 30 Days Starter Set comes with an Edition Glass Bottle made from durable borosilicate glass. Unlike plastic, glass does not retain odors or flavors from previous drinks, so your water stays clean-tasting even after repeated use. The 20 fl oz (about 590 ml) size fits most cup holders and is easy to carry to the office or gym.
Borosilicate glass also handles temperature changes well, meaning you can use it for cold or room-temperature water without worrying about thermal shock. Just keep in mind that glass is heavier than plastic and can break if dropped, so it's best suited for home, desk, or bag use rather than rugged outdoor adventures.
What flavors are included?
The Starter Set contains 60 Microdrink cubes divided across five flavors. While the exact flavor lineup may vary by region, each cube is designed to dissolve quickly in still or sparkling water without artificial sweeteners. The variety lets you rotate flavors so you don't get bored, which helps you stick to your hydration goal.
If you are new to waterdrop, the 5-flavor selection gives you a chance to sample different taste profiles before committing to a larger box of a single flavor.
Frequently asked questions
- How do I use the glass bottle for the first time?
- Wash the glass bottle and cap with warm soapy water before first use. Rinse thoroughly. Fill the bottle with still or sparkling water, leaving a little space at the top. Drop one Microdrink cube into the water, close the cap, and wait about 1-2 minutes for the cube to fully dissolve. Shake gently if needed, then enjoy.
- How many cubes should I use per bottle?
- Use one cube per 20 fl oz bottle. Adding more than one cube may result in an overly strong taste. The 60 cubes in the set are designed to last 30 days when you drink one bottle per day.
- Can I use the cubes with hot water?
- Microdrink cubes are designed for cold or room-temperature water. Do not use them with hot water, as heat may affect the flavor and the cube's dissolving properties. The glass bottle is not intended for hot beverages. Stick to still or sparkling water at cool or room temperature for the best experience.
- How do I clean the glass bottle between uses?
- Rinse the bottle with water after each use. For a deeper clean, wash with mild dish soap and a bottle brush. Avoid abrasive scrubbers that could scratch the glass. The bottle is not dishwasher safe, so hand wash only. Let it air dry completely before storing.
- What if I don't like one of the flavors?
- The set includes five different flavors, so you can simply skip the ones you don't enjoy and use the others. If you find a flavor you love, you can purchase additional boxes of that single flavor separately on the waterdrop website. Use the Starter Set as a tasting kit to discover your preferred flavors before buying larger packs.
