Honesty, I've found a few options here, maybe something will suit your preferences. 🧋 if you don't want another travel cup you can get a mason jar attachment like this one: https://www.jarware.com/products/stainless-steel-2-in-1-drink-and-fruit-infusion-lid-for-regular-mouth-jars stainless steel + ceramic lid + silicone plug: https://elementalbottles.com/collections/mugs-tumbler/products/artisan-tumbler can't say how safe would this be in a car but mayyyyybe it's an option too? https://www.instagram.com/daultpottery?igsh=MTV1MmN2cTJ1cjd3MA== one of my dreams these days: https://true-fruits.com/Trinkaufsatz I've found a few brands that do cups in this style, they look a bit odd though so I'm not so sure if having a China dropshipped full glass mug will be environmentally alright: https://www.amazon.com/Silicone-Reusable-Beverages-Capacity-Including/dp/B0DFHB3C8D
