Purchased in September of Reiwa 5 (2023) and used a few times for my son's lunch, but it wasn't enough, so I bought a Foodman 800 and haven't used this one since. The original packaging and instruction manual are included. I threw away the movable divider immediately. It closes tightly, so it doesn't leak even when standing up (it never leaked). I found it difficult to open, perhaps because I don't have much strength or couldn't get the hang of it. Dishwasher and microwave safe. Please understand that there may be minor scratches from washing. Please refrain from purchasing if you are concerned about this.
