Is the Light Sky Blue tumbler BPA-free and safe?

The Light Sky Blue powder coating is food-safe polyester with no BPA, lead, or phthalates. The flip straw lid uses BPA-free polypropylene and platinum-cured food-grade silicone. All materials meet FDA standards with third-party testing confirming zero chemical leaching. Completely safe for daily use by all ages.
