I have about 12 in all....4 kareha and 10 wakaba. These were just purchased from autobacks in Japan about a week ago, so yes, they are authentic. Comes in reflective magnet for inside, or reflective magnetic for outside. $10 shipped each, takes 2-4 days. If you want the pack with both suction and magnet $20. East coast OK too, ive sent numerous to florida.

These usualy go in about a week on honda tech, so if you want one let me know, better yet, paypal me. Paypal address - seantimson@yahoo
many people here can vouche for me that these are good quality with fast shipping.
