Ask HN: Water jug with 9-5 markings by HN user

I remember someone from HN once posting in one of those "what products / companies earn you side-income" posts, that they had a small company making high-quality water jugs with 9-to-5 markings on them, using high quality glass and materials.

I wanted to check it out again, but I can't find it now.

Does anyone know what I'm referring to to give me a link please?

(possibly the creator himself, even!)

Thanks
