Thank You Stickers - Set of 4 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 was pleasantly surprised by how much presence they have and how well they look! I love 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 things(^^) 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, ranging from approximately 450 to 500 stickers per roll, depending on the pattern and lot. (Recently, we found a roll with only about 450 stickers out of a product we purchased as 500 stickers per roll, and we contacted the manufacturer, who said they would work to improve this 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, so it's impossible to tell without opening them (><) Therefore, please don't worry too much about the number of stickers and use them generously, with a relaxed feeling. I also use them without worrying about the number(^^) You can also add more rolls or change the patterns, 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 thank you for your understanding.)
