Hi, thanks for interest and enquiry! Bamboo liners are for use with cloth diapers to make disposing of poo easier.
Unless the elderly is wearing cloth diapers, this will not be of much use.
If it's female elderly, she can look at our bamboo panty liner which can be worn for mild uninary incontinence. The listing is: http://list.qoo10.sg/g/412382791
Hope this answers your queries and please do not hesitate to let us know should you require any further queries. Many thanks!
