We are currently in a silly situation when dealing with refillable products for home, and I was wondering if anyone else had any ideas.
If I wanted shower gel (for example), all the refillable locations require a bottle with the capacity printed on it, and for it to be empty. And basically I don't want to wait until my shower gel is out completely before getting any more, so I would want an intermediate container however I cannot find a 1l bottle that has the capacity embossed on it so that I can take it to the refill station, and bring it home. I really don't want to buy another small plastic bottle with the capacity on a paper label that does one refill of the gel, and would have to be replaced when the label comes off.
Hmm I might've been overambitious. Searching "glass water bottle with measurements" gets a few Amazon results but so many of them have "motivational" time labels but no ml markings...
There are quite a few listings for chemistry reagent type containers, too, which could maybe work?
The best thing I've found is this from Dunelm might be what you're after?
