This is a product I regularly purchase online. However, when I tried using it this time, it felt a bit too loose and I couldn't use it. I have quite a few of them, so I'd be happy if someone who can use them would take them. Small size Approximately 13.0 x 10.5 cm [When folded] Please note that it feels a bit roomy. I tried using them, so there are [46 sheets set]. I opened the package once to count the number of sheets, but it's a zip-lock type, so it's sealed. Please refrain from purchasing if you are sensitive to such things.
