This has two ends. One is the pencil and the other one is the bristles! I only started drawing my eyebrows a few months ago and I started with this product (due to a friend recommendation). Initially, I couldn't really get the hang of it but after a month of practice, I can officially say I'm a huge fan of the pencil. The bristles are a bit hard on the skin, but it helps to make the look more natural after drawing. This can last quite long, usually it will still stay after a whole day of work (10-12 hours?). Sometimes it can stay after I've exercised. Another great thing is you don't even have to sharpen at all! Be careful with the pencil part though as mine broke a bit before. There are some YouTube tutorials that shows how to use this pencil and it's pretty useful! All in all, it's really cheap if you buy from Korea, probably less than sgd4? Plus their refill pack is even cheaper.
