GONNA LOVE THIS! — BNTO Canning Jar Lunchbox Adaptor (Wide Mouth)

Wow! When we first saw these BNTO (ben-toh) Wide-Mouth Canning Jar Lunchbox Adaptors by CUPPOW, we immediately knew that they were WAY over the top on our Cool Stuff scale! AND, they check off all of the boxes for the kind of discoveries we want to find and bring to you at Pretty Things & Cool Stuff.

Here's the magic: Use a BNTO to turn a canning jar into a lunchbox! Yes! Simplicity is the root of all genius!

When I first showed a BNTO to my husband, Bill, he took one look and said, "I'd use that in a second!" He then went on to talk about how it could help him eat healthier at work — really! — and he started brainstorming about how he could cut up different vegetables and take peanut or almond butter or hummus or guacamole or salsa and package them together in one neat, portable AND very functional package.

What about fruit or granola and yogurt or soup and crackers or chips and dip or cookies and milk? You're only limited by your imagination!

Just check out the video and pictures!

Another awesome thing about the BNTO is that it let's you get away from BPA-laden plastic and use what has always been the best for storing food — glass! The 6-ounce BNTO cup is made from BPA and phthalate-free, food-grade, recycled rigid plastic that is reusable, and is dishwasher safe (top rack only, please). Both the BNTO Canning Jar Lunchbox Adaptor and its packaging are made in the USA from 100% recycled materials. 

Here's the story about how the BNTO WIDE Canning Jar Lunchbox Adaptor came about for the folks at CUPPOW:

Canning jars are designed to store food safely and make an awesome lunchbox: they are easy to clean, cheap, and you can microwave them! The only problem is that sometimes the foods that taste the best together don’t travel well together. So we took inspiration from Japanese bento boxes and created a conveniently shaped insert that separates a canning jar into two compartments so you can mix or dip like a champ.

This first offering from our BNTO line holds 6 fluid ounces (3/4 cup) and is built to fit snugly under the standard metal lid of a wide mouth canning jar. BNTO should provide the perfect companion for all your food adventures!

And if all of the above isn't enough, two-year-old CUPPOW is an amazing company with a great mission and core set of operating values and actions centered people and the planet.
