I use this Pyrex Simply Store 10-piece set for weekly meal prep and it does the job well. The rectangular glass containers stack neatly in the fridge, and the lids fit securely, so I have not had leaks in my bag. Glass means no staining from tomato sauce and no lingering smells, which I really appreciate. They go from fridge to microwave easily. The only small thing is that the lids need a firm press to seal properly. Overall a solid, durable set for anyone organizing meals ahead.
