I know going to the 'eye doctor' or optician can be expensive, but what you could try is this:
Some opticians, if you go in and ask for 'blank' or plano contact lenses will give you a set free, so you could get these, which will have all the size/shape details on them.
But- I recognize the brands you currently have, and I have used them when my circle lenses have been lost/had not arrived in time, and they fit me and my spec is the same as those you are looking at on pinky paradise, so if they fit fine, the PP should be fine.
But do remember to clean them, clean the case, and change the case every three months.
(Before anyone asks I have glasses, from the 'eye doctor' and have been fitted and measured for contact lenses, and wear them more often than glasses)
