      never mind the bpa when there’s the microplastics issue.

      Besides: Most recent food grade plastics are BPA free now.

      most travel drinking vessels (even metal) should be replaced every 10-20 yrs. Plastic even sooner than that (2-5). And if you have any deep scratches or visible on a surface(even metal) it should definitely be replaced immediately.

      I don’t trust the plastic vessels anymore because they should be replaced because of microplastics. Whenever you twist a plastic cap on something with an internal helix, you’re grinding more microplastics into your drinking liquid. Try to get the screw tops that have the helix on the outside and a silicon seal to have a barrier.
