Thank you for viewing. This is a set of 3 Hello Kitty "kakattel" (calling) keychains. These keychains lit up when a call came in on a mobile phone back then. The batteries are dead, so I haven't been able to confirm if they still work. I think it's rare to have all three colors. Recommended as a collector's item. ✾ Made in 1997 ✾ Please refrain from purchasing individual items. These items have been stored at home for a long time, so please understand.
