A Classic.
Shu Uemura is known for this product. It is the best tool I have in my collection. Those with small and straight lashes, look no further. It is worth the price and gives perfect doe-eye lashes. I've never had any problems with this tool and it is much safer to use near the eye than any cheaper eye curler.
The results are a dramatic curl, looks great naturally or use mascara for even more.
For Asian eyes: Essential. Japanese eye curlers have a big name for a reason. If you suffer with small straight lashes that usually hold zero curl like I do, use Shu Uemura. The results are stunning on asian eyes.
