Mighty Nest is one of my favorite places to go for reusables and sustainable products. I discovered this family owned business years ago googling for glass containers and fell in love. They are full of great products that give you healthier options for you and your family as well as loads of information with great blog posts.

I have switched out all my plastics to glass like this set from Wean Green. Wean Green is family owned and their glass containers are for storing, freezing, reheating and are droptest approved.

LunchBots Thermal 16-ounce Insulated Food Containers keep hot foods hot for hours – without plastic coming into contact with your food. My pho is waiting 🙂 If you fill it with fruit salad – they keep cold foods cold too!
