Small frame for Japanese paintings and oil paintings, SM size

This is a Japanese-style painting I received. Although it's a Japanese painting, the frame used is the same as for oil paintings.
Size of the painting area: 16.5 x 23 x 1.9 cm
Size of the frame itself: 20.1 x 27 x 3.3 cm

I purchased a different frame that matches my room, so this one is no longer needed. The size is measured by an amateur. Please refer to the photos.
As shown in the 9th photo, there was one spot of rust. It does not affect use.
In the 11th photo, the top edge of the frame has some pooling of paint, but it is not a dent or chip.
The price is set for simple packaging wrapped in bubble wrap and sent from a post box.
