Thank you @Cassie Ann Hoffman for the information. Yes, the best thing about pocket garbage bin is that many peoples dispose of used chewing gum in their purse, and they often get the gum stick to their purse damaging it, this device will not stick to the chewing gum because of its internal design.
So, you can store any kind of micro garbage in it and will be safe.
Also, I edited this comment and in the previous I used the word females because I did a Q&A on chewing gum vs purse problem on peoples near by and the word was just based on the data.
If there is anyone who is not comfortable with it, I apologize: I have all the love and respect for our women and please take it in a positive way.
