The Seal Cup Mini holds ⅓ cup (78 ml) and measures 2 5/8 inches round by 1 1/2 inches tall. The stainless steel lunchbox cup is ideally sized for packing to-go the little extras that make lunchtime at school, work or outdoors delicious. It’s perfect for salad dressings, crunchy toppings, croutons, seeds and nuts, dips and more!
- 🔄 NESTS & STACKS: Container nests and stacks one inside the other for compact storage in your cupboard. This eco-friendly ECOlunchbox container is part of the 6-piece Blue Water Bento Seal Cup Collection, which includes the Mini, Small, Medium, Large, XL and Jumbo Seal Cups. Each container features an embossed ocean motif on its colorful lid. The ocean designs celebrate ECOlunchbox’s mission to make your lunches greener and keeps our oceans bluer by eliminating dangerous plastics from lunchtime.
- 🌱 100% PLASTIC FREE, NON BREAKABLE & BPA-FREE: Made from the highest quality 18/8 stainless steel and silicone components.

Our stainless steel food containers are third party independently tested for food safety compliance with USA and EU standards.
- 🧼 DISHWASHER SAFE: All parts of our metal and silicone bento boxes are dishwasher safe, including the lid! No need to hand wash silicone lids separately from the container bases like with other brands with lids made from plastic or with embedded gunky gaskets.
- ❤️ TRUSTED MISSION-BASED BRAND: California eco mom and environmentalist Sandra Ann Harris designed the original ECOlunchbox stainless steel food container more than 10 years ago. The woman-owned company continues as a mission-based, family-owned business dedicated to helping people reduce their dependence on plastics for health and environmental reasons.
