Review (4/5): Not a bad set!
One star removed because of the limited sizes, packaging the adhesive tabs, the odd number of nails included, and the fact that I think the transparent nails would probably look better with a white background instead.
These nails came in 10 sizes - 0 to 9. Other brands will usually come with more (smaller) sizes. I do have small hands, so this might not be a problem for most folks. For my pinky, I had to file the size 9s to fit.
One of the two sheets of adhesives came a bit crumpled. Though I didn't use the tabs - I use liquid, which wasn't included - I still think it's important to package everything a bit more carefully.
As for the odd number of nails, not every size came in a pair. I believe size 4 had only one nail, and 7 had three.
After applying, I do think a white background, rather than transparent, would have looked great. But, it's up to you. I would have painted the well side with a white gel polish or acrylic paint first, if I wanted to try again.
Application was pretty standard, nothing out of the ordinary. They're a bit thin, and flexible, making them easier to shape around more curved or flat nail beds. Despite how thin they are, they still feel sturdy. And because they are transparent, it's important to make sure ALL bubbles are gone if using liquid glue. I feel the tabs would be very visible, so glue is probably the best option. The length is great as well, these would probably be considered medium-long in typical drugstore brands.
Also, please note that these are more of a burgundy color, not red as shown.
