okay hi this is wine and spirit d let me show you these are the beads that are used for cleaning out wine bottles usually when you have a wine bottle it's so narrow that you can't get in there with a black and there's a few reasons why you would use these beads to clean it up by simply adding water and soap and just putting the beads in and shaking it up and it gets around the corners that cleans out everything now I personally buy antique frequently and sometimes the bottles I have bought are like a hundred years old and there's been times where I've cleaned out the bottle and actual Roach eggs have come out in the bottle I don't know whether the roach eggs are 60 year old Roach eggs or fresh fruit eggs but I know I don't want roaches so it's best to make sure you do a thorough clean and when you put these beads inside of the bottle and you close it up and add some water and soap and shake it it the beans go along the corners and just pretty much pools anything in there off cobwebs or whatever now that's just for me because I like antiquing however there's other uses for example if you have an expensive wine bottle that you like to keep and you like to replace it with a cheaper wine because that's what you have I don't judge but you can clean out the bottle with these little beads and then pour the other wine into the bottle well overall I like them I find it useful I did not know they existed before and I am going to continue to use them to clean up my antiques thank you
