Stock level at Kotobukiya Radio Hall.
Comes in two versions - Sheryl Nome and Ranka Lee, but both has the same soy sauce flavor. Pre-order of the ramen set (20 cups per set) from Bandai Premium started on January 29th. Production was limited to just 5,000 sets - a total of 10,000 cups.
Looking at the many crates of cup noodles stocked up by Kotobukiya Radio Hall in the last image, I believe many other stores did the same as well. ^^
Each set is 5,250 Yen (inclusive of tax). Each cup is priced at 262 Yen (inclusive of tax).
A review on the noodle can be seen in this previous posting.
