Thank You Stickers - Set of 10 Rolls (Approximately 450-500 stickers per roll) The stickers are 2.5cm in diameter. I was worried that 2.5cm might be too small, but I tried sticking them on a size-3 long envelope and they looked more substantial than I expected, and I really like them♪ These are imported goods, so they are not as perfect as Japanese products, but they are cheap, so you can easily stick them on(^^) Depending on the lot, there may be some printing smudges, color bleeding, or individual differences in color and shade, but please rest assured that we do not sell "defective products that cannot be used as thank you stickers." Regarding the number of stickers, it seems there is quite a variation, depending on the pattern and lot, with approximately 450-500 stickers per roll. (Recently, we found a roll with only about 450 stickers out of a product we purchased as 500 stickers, and we contacted the manufacturer, who said they would try to improve it in the future, but honestly, I don't know how much I can trust that.) There are rolls that are properly wound with about 500 stickers but are smaller and lighter than others, and there are rolls with only 450 stickers that are the same size and weight as good ones, and there's no way to tell without opening them (><) So, please don't worry too much about the number of stickers, and I hope you can use them generously, with a roll full of stickers. I also use them without worrying about the number(^^) You can also add more rolls or change the design, so please feel free to contact us if you would like to make any changes. (※If you wish to make changes, please let us know before purchasing, and we will create a dedicated page for you, so please understand.)
