Just the right size and easy to put in.
Exactly what I’ve been looking for to replace ones I had worn for the last 30 yrs.  (they had been lost at hospital after a nurse removed them prior to a neck surgery). They are just the right size and easy to put in.  I just hope they hold up and don’t turn on me.  This size and thickness is very hard to find!  So far I’m satisfied with my purchase.
