I don't know the details, but I've gathered some yellow-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 sticker was. Please be aware of this before purchasing. The quantities vary, but I haven't used any of them. I plan to list other colors as well. Stock is running low. I can't lower the price any further. First come, first served!
