The Glass Lunch Pot from Black Blum combines modern design with practical retro charm. Its stainless steel body and wooden fiber polymer base offer a stunning material choice. The result is an innovative and durable solution that lasts. The silicone lid with a smart vent adds convenience, allowing the lid to stay in place during microwave or oven heating to prevent splatters. The inner container is made of hand-blown, high-quality borosilicate glass – lightweight, strong, recyclable, and stain-resistant. The base, made of polypropylene with 30% sustainably sourced wood fibers, features a silicone ring to protect the glass and prevent slipping on vibrating surfaces like train or airplane tables. BPA-free, 100% leak-proof, dishwasher-safe, suitable for oven and microwave, and freezer-safe.
