What was once a symbol of your eco-friendly lifestyle has now become a status symbol - with people owning whole walls of reusable bottles to show off online....
Apparently, almost all mass-produced bottles have lead-based solder in them, including the expensive ones. Lead-free solder is expensive, so there’s not a lot if brand that exists with safe solder. Also, the solder dot is on the outside, at the bottom of the flask, so as long as it is protected from erosion by use of a cap-like structure, you’re safe.
Updated my old comment. Lead is present as a solder dot in most of the expensive flasks, including the Stanley. Mine happens to have a cap over the sealed area. My particular flask is made of stainless steel grade 304.

I’m talking about the steel in general. There have been many recalls of items made using stainless steel that was contaminated.
