My essential... eyebrow scissors. Trimming scissors.

Instead of having to draw my eyebrows, they grow really fast

It gets messy as it grows. These are the scissors I often use in such situations.

I bought this at Aritaum, and I like that the comb detaches, so you can wipe it clean after use or if foundation gets on it. Best of all, I've used it for a long time and the cutting power is still really good, so I recommend it!
You can buy it at Aritaum for 2,000 won... and I highly recommend it to people like me.
