## Questions & Answers

**Q: Can each container be used separately or must they all be used together in order for it to close?**
A: They can be used separately. It's actually pretty neat.

**Q: Will an ice pack fit in these?**
A: No.

**Q: How many times does the product last? Like when should I change a new one due to degradation in material (plastic)?**
A: I've had plastic bento boxes before in the past and it honestly depends. If you take care in cleaning it, overall it can last for a long while (like 2 to 3 years). At least for me. It can probably last longer than that depending on use. I just use it very frequently so it's gotten a lot of use.

### ⭐⭐⭐⭐ A lovely bento box
*by T***T on January 10, 2026*

This lunch box is a good size for what I needed. It’s deeper than others I’ve had, which I like, but still nice and compact. I love the color and how the lid looks like wood. Each container has its own lid to prevent leaks, which I appreciated. It’s very convenient to prep my lunch in here the night before, tuck it into the fridge, and then put it in my bag to go to work. Pulling it out for mealtime I can use the little sauce container for salad dressing or nuts etc. My only disappointment is that while mine has a fork and spoon, it did not come with a knife, though it has space for one there. Now I need to find one that’s the right size, so that’s a little disappointing, but otherwise I’m very happy with it.
