Genshin Impact: A Tour of Teyvat - The Sky Garden and Moon's Prayer This is a postcard distributed as an entry bonus at the Marine Tower event. Both serial codes are unused. Although it is new and unused, please refrain from purchasing if you are concerned about minor details, as it has been stored at home. Shipping will be via either Rakuraku Mercari Bin or Yu-Yu Mercari Bin. I will decide which to use. Thank you.
