Instant purchase is OK. Material: Brass Shipping will be via standard mail, so we are not responsible for any issues during transit. For an additional 100 yen, we can change to Mercari delivery with insurance. If you would like to make this change, please let us know before purchasing. Due to overseas production, there may be scratches, burrs, distortions, and uneven plating during import and production. We appreciate your understanding. Thank you (⁎ᴗ͈ˬᴗ͈⁎)
