Our Microenergy Collection is here to provide you with that extra boost you need to get you out of that energy slump or for long days in general. Each Microenergy cube contains around 90mg-160mg of natural caffeine.

All our cubes are gluten-free. As for vegan, there’s just one exception: GINGER LEMON isn’t vegan, as honey is used during its production, even though it doesn’t appear in the final ingredient list. All our other cubes are vegan.

Vitamin C, B12, folate, niacin, and pantothenic acid contribute to the reduction of tiredness and fatigue. A varied and balanced diet as well as a healthy lifestyle are important.

The engraving costs €12.90.

At the moment, the engraving location cannot be selected and is fixed. For Explorer bottles, the engraving will be centered, while for all other bottles it will appear in the lower third of the bottle. After entering your desired text or emojis, you’ll be able to preview a mockup before confirming the engraving.

Our engraving tool supports a wide range of characters, so you can personalize in your own language, style, or with a bit of flair. You can choose from a selection of emojis in addition to up to 15 characters of text (T&Cs apply). Supported characters include:

Numbers: 0123456789

Standard letters (upper & lower case): ABCDEFGHIJKLMNOPQRSTUVWXYZ / abcdefghijklmnopqrstuvwxyz

Accented & special Latin characters, covering most European languages (e.g. À Ö ü ç ñ ø ß Ł ő ș and many more)

A few Greek characters: Δ Ω μ π

Punctuation & symbols: "" - . ? ! ~ * & # : ] [ ( ) |`

Note: If a character you'd like to use isn't on this list, our engraving tool won't be able to process it — we recommend double-checking your text against the list above before submitting your order.

Not every product comes with an engravable finish. If a bottle or cap offers this option, you'll find an engraving widget directly on the product page, where you can type in your text and preview it before adding it to your cart. If you don't see the widget, that particular design isn't engravable — but plenty of our bottles are, so there's likely a personalized match for you.

One more thing to keep in mind: engraving results can vary slightly depending on the product's coating and finish. This is completely normal and not a flaw!

Unfortunately, engraved items cannot be returned.
