Handmade kitchen goods. I think it's convenient to hang it near the coffee maker. Gusset: Approximately 2.5 cm Interfacing is used on the outer fabric. Holds about 50 filters for 2-4 cups. Although I have finished it carefully, there may be imperfections such as distortion or misalignment. I hope that those who understand this will purchase it. Please note that it will be shipped folded.
