The size is very small and the silk covering (or whatever they call it) makes it really easy to insert and take out. So that's the good part. The worrying part is the fluffy bits around where the string is - when you take it out of the packaging there's lots of fluff around it and it made me anxious everytime. Also,the packaging separates into three, so everytime you use one you have bits of plastic everywhere.
Very comfortable to insert and remove
The fluffy bits make you worry, and too many bits of plastic wrapping
