We have a recent post for 16pack, however 12 pack seems cheaper at almost half the price with 20% off with subscribe and save from 13.49 to 11.19. Cancel subscription after delivery if you need to. I have noticed that they are Made in Japan after doing some research. Good value for money and 1000 cycles life.
