The kaomojis can be scrubbed off so do wash with care... The aesthetics and simple and fun-looking! There wasn't any smell of plastic when I took off the packaging. The bento boxes come with a rubber band to hold it together but the rubber band slips off easily. So I recommend covering the bento boxes with a cloth, and hold it together with the rubber band! Other than that, the sealing quality is not that bad either. Simple and cute to store light food!
