I'm not entirely sure, but I've gathered some brown-colored items. I just bought them, but they're old, and the plastic parts are deteriorating and falling off. The lid functions perfectly fine. Also, there's some stickiness where the stickers were. Please be aware of this before purchasing. Some of them cost 3600 yen each. The amounts vary, but I haven't used any of them. I will be listing green-colored items as well.
