I've been using the GLASS LUNCH POT LARGE for work lunches and it holds a good portion of soup or leftovers. The borosilicate glass bowl is microwave safe and the wood fibre base makes it easy to lift out when hot. It's genuinely leakproof, so no worries carrying it in my bag. The stainless steel lid feels sturdy. Everything is dishwasher safe too, which is a big plus. The only thing to note is the steel lid can't go in the microwave, but that's clearly stated. Good eco-friendly option overall.
