Individual Intimate Rose medical-grade anal dilators are great for adding on to existing sets if more sizes are required, or for when just one or two sizes are needed. 
 
Always use a water-based lubricant with these dilators, as they may be damaged by others.
 
Rectal dilators are a useful tool to address painful pelvic floor issues such as levator ani syndrome, spasms of muscles around the anus, pelvic pain, proctalgia fugax, functional constipation, and stenosis of the anus or rectum following surgery or certain cancer treatments.
 
They are used to gently stretch and open the anal canal.
Some symptoms of pelvic floor dysfunction around the anus include:
 
Pain with sitting
Sensation of spasms at the anus
Pain or difficulty with bowel movement
Stenosis from anorectal radiation therapy
Scars from surgery
Pain following a fall or injury
Pain with anal intercourse
Pain in the rectum with orgasm
 
Note a handle is available to aid use, but is sold separately.
