620 yen → These are handmade items using A4 design paper. Sometimes, things don't fit in a standard envelope, but are too big for a non-standard envelope, right? I've added a flap so you can seal them. You can use them as envelopes by attaching an address label. ⚠️ Even if they are thin, they are non-standard size. ⚠️ Address labels are not included. Available in Western and flat bag styles. Both are made so that the size of the part without the flap is about the same. Length x Width... 17.5 x 14 cm There may be some variation. I make them carefully, but they are not perfect like commercially available products. I look forward to purchases from those who understand handmade items.
