Currently living for my new Tarte emphasEYES™ Amazonian clay waterproof liner & brush, it glides on beautifully and is waterproof. It is a cruelty free formula – not tested on animals. It comes with a double ended brush for smudging and lining, it takes practice but it definitely works very well. My advice is to take your time with it, line gently and build your wing using tape around the end of your eyes. See this very helpful Pinterest tip here and here also.
PS. I bought mine at Sephora in the USA, not sure if it is available in Singapore (check Sephora outlets).
