Thank you for viewing! These are small paper envelopes (pochibukuro) made from kraft paper. I've stamped them with my own handmade stamps using oil-based ink. They are a botanical pattern series. 4 patterns x 5 sheets each, for a total of 20 sheets. They are sized to fit folded bills (folded in thirds). The kraft paper is 70g/m², so it's sturdy. These are handmade items. There may be slight variations, ink smudges, etc. Please understand this before purchasing. Shipping with tracking (anonymous) is available.
