I recently got those amazing Naruto lenses from Coloured Contacts UK!
First of all they are really easy to put in and also comfortable to wear which is the most important thing about contacts!
Also they are super bright and the effect looks amazing even with my brown eyes. I often have a hard time to find covering ones for dark eyes, but those are really good – definitely recommendable!
Here is the Link to their Sharingan contacts – they have a huge variety, perfect for all Naruto fans 🙂
