Where to buy good quality meal prep containers?

I recently started meal prepping and I‘m using some old plastic containers I have lying around at home. I have three now but they are quite small. I‘m planning to buy a few more to replace the old ones and I also need some bigger containers. I‘ve been looking online, Amazon, eBay, AliExpress but there is so much to choose from. I‘d love to hear your opinion on the best ones you‘ve used. <br><br>Does anyone know of any good quality brands that fit all kinds of food, no leakage, microwave and fridge safe? How many do you need in a week for a single person? I‘ll be preparing lunch and snacks, only. <br><br>Thank you.
