Here’s what consumers have asked with answers from Twinklens staff and previous consumers.
There are other places that are FDA certified that sell contacts, but I haven't found many that offer that at a better price point.
Yes! I showed up to work with a pair of purple contacts in and my friend was absolutely in love with how they looked!
No. I have multiple different pairs of contacts from them, have use them repeatedly, and have never had any negative reactions from them.
