This item was purchased about a year ago and has been stored at home. I am selling it because I no longer plan to use it. Braun CCR5 Clean & Renew Cartridge ● Alcohol cleaning solution that can even disinfect ● Approximately 30 cleanings are possible with normal use ● Made of alcohol, so it evaporates naturally ● Even if you don't use it every day, it is recommended to replace it approximately every 8 weeks ● Refreshing lemon scent
