I picked up this Snapware® Total Solution® 10pc Set Round Meal Prep for weekday lunches and it does the job well. The 3.8 cup round containers are a good size for a full meal, and the airtight, leak-proof lids have held up so far — no spills in my bag. Five containers plus lids means I can prep a few days ahead. The lids need a firm press to seal properly, but once on they stay put. Handy set overall, just wish the round shape stacked a little more neatly in my cupboard.
