Will be sold as a set. 20 pieces of 40g make 800g. I don't think there's any unpleasant smell, but please refrain from purchasing if you are concerned. The color in image 3 is closest to the actual color. I will compress it to size 60 or 80 for shipping, so please be aware that the labels may be creased or the rolls may lose their shape. The shipping method may change between YuYu and RakuRaku. If you wish to receive a discount for purchasing multiple items, please let me know in the comments or discuss it in the comment section of the bundle request. The amount saved on shipping costs will be deducted.
