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 vegan and gluten-free.

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.

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.

Unfortunately, engraved items cannot be returned.

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.

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!
