Bests & Worsts Reviews from Amazon

For some reason I expected these were going to be similar to a Pyrex glass and that they would be oven proof like a custard cup. I wanted to make custards, grapenut, and pumpkin puddings in them in the oven and then just cover them and put them in the fridge. I know they don't say they are heat proof in the description. The description says they are microwave, freezer and dishwasher safe. So my mistake in ordering them. BUT the box they come in has little pictures of a microwave, a dishwasher, a freezer and AN OVEN......EDIT: Since first writing this review I have baked custards in these cups and they definitely are oven proof. The description on Amazon should make this clear. I really like these for baking and for storing small items in the fridge. Also, in response to the reviewer who said the lids look like they would not last very long I'd like to attest to the fact that they are VERY sturdy and hold up very well. You can wash them in the dishwasher too.
