Are the lids leakproof?

No. The lids sit on with a simple seal, so they handle fridge storage but can leak thin liquids if tipped. Keep saucy or soupy foods upright in a bag.

Can the glass go in the oven?

The glass bases are generally oven-safe for reheating, but the lids are not. Remove the lids before any oven or broiler use and let the glass cool before washing.

Is the whole set dishwasher safe?

Yes, the set is listed as dishwasher safe. Top-rack washing helps the lids keep their shape and seal longer.

How does it compare with Pyrex or Snapware?

It is simpler and cheaper in build. Those brands offer locking lids and wider size ranges; this set gives you plain glass containers with basic lids.

What sizes are in the 8-piece set?

Eight pieces means four containers with four lids, in a few round sizes for leftovers and small meal prep. Check the listing for exact capacities before buying.

Can the containers go from freezer to microwave?

The glass handles freezer storage and microwave reheating. Avoid sudden temperature swings, such as freezer straight to a hot oven, which can crack glass.
