It started with one question.

Two similar water bottles, tagged 1 and 2, side by side
"Is this mine?"

Our water bottles kept getting mixed up.

I got tired of picking one up, taking a sip, and wondering whether it was mine.

So I tried something simple. I numbered them.

I had my number. My husband had his. And suddenly, there was nothing to figure out.

That little idea became H2Otag.

FAQ

A sheet of waterproof, peel-off numbered stickers (1–4) you stick onto water bottles, mugs, or tumblers so everyone in the house or on the trip knows which one is theirs.

One 6"×4" sheet with four individually peel-off numbers, 1 through 4.

Any smooth, clean, dry surface — stainless steel, plastic, glass, and aluminum bottles, mugs, and tumblers all work great.

Yes — the vinyl and adhesive are built to handle daily use, spills, and repeated washing.

They're designed to stay firmly in place, but they will peel off a smooth surface if you ever need to. A little rubbing alcohol takes care of any leftover residue.

Four covers most couples, families, or roommates — with a spare in case someone ends up with more than one bottle.

Mine or yours?
