This is a set of 70 small bottles, each with a diameter of 2.2cm, a height of 6cm, and a capacity of 12ml. I purchased these new and unused on Amazon and used them once for a sand ceremony at my wedding. Therefore, please be aware that some sand may remain inside the bottles, and there may be small scratches. Please only purchase if you understand this. Please note that I have intentionally not washed the bottles. When used for a sand ceremony, depending on the type of sand, approximately 20g of sand can be accommodated. I have attached a photo showing 17g of sand inside. I debated whether to use a spoon or small bottles for the ceremony, but on the day, everyone could pour the same amount, and we could tell how many people had participated by counting the remaining bottles. My wife and I agreed that using the bottles was a good choice. Since they are bottles, there was almost no risk of spilling. I will ship them in the same way they arrived from Amazon, with about 20 bottles per bubble wrap bag. Amazon shipped them in a paper bag instead of a cardboard box.
