Hmmm be careful with those ones, you glue them on & god forbid after a few too many drinks & getting a bit hot & bothered after a dance or two, you'll have an epic eyelash laying askew across your face lol
I do extensions, partials or full, I use varying lengths & thickness to ensure they look as realistic as possible. I do 'weekend' lashes that last 3 days or so. 'Friday Night Lashes' that last literally for the night or actual extensions, which take the longest, but last anywhere from 3-4 weeks.
The BIG W ones are just sets, that you manouver on with a stick or strip of glue & they never fit the eye properly lol See how you go, you may be better off without them.
I thank god I have decent lashes & don't need them, I tried those tacky store bought ones years ago in London & I felt like I wanted to scratch my eyes out after about an hour lol
That being said though, some women make em work & like them. Just give it a shot & see how you go.
