Durable, Modular Non-Plastic Lunch Containers with Replaceable Lids

The user is explicitly seeking microwaveable, non-plastic lunch containers due to health concerns about heating plastics. While glass and silicone options exist (as comments suggest Ikea, Pyrex, Amazon), a common pain point for all food storage is the lid's durability and replaceability. An opportunity exists for a premium brand offering a modular system of glass containers with highly durable, non-toxic (e.g., high-grade silicone, sustainable wood/bamboo composite, or stainless steel components), and easily individually replaceable lids. This addresses the desire for a healthier, long-lasting solution by tackling the most common failure point and reducing waste from discarding entire sets due to a broken lid. The UK specific mention suggests a market for a locally relevant or high-quality imported solution.
