Sharp So Simple Waterproof Pencil Liner
CLIO's ultra-thin waterproof pencil liner: a 0.14g retractable, very fine pencil with a silicone-resin and wax formula that sets quickly, for tightlining and fine lash-line definition.
Buyer verdictA cheap, precise, long-wearing liner that's a favourite for filling in between lashes. The tip is very fine, so it runs out quickly, and it doesn't do bold wings well. We don't compare prices because Amazon listings aren't the same size.

Overview
Key ingredients
- Black iron oxide (and other pigments by shade) The colour
- Trimethylsiloxysilicate Film-forming resin that makes it waterproof
- Cyclopentasiloxane and methyl trimethicone Volatile silicones that evaporate so it sets fast
- Synthetic wax, ceresin and carnauba wax Give the pencil its firm, glide-on body
What it is
CLIO is a Korean makeup brand known for long-wear eye products. The Sharp So Simple Waterproof Pencil Liner is a retractable pencil with an ultra-fine tip, made for drawing close to the lash line and filling in the gaps between lashes. Each pencil holds 0.14g, and Olive Young often sells it as a double pack. Olive Young bills it as its number one eyeliner.
The Korean ingredient list for the black shade is short. Black iron oxide comes first, then trimethylsiloxysilicate, a film-forming silicone resin, and the volatile silicones cyclopentasiloxane and methyl trimethicone. Waxes follow: synthetic wax, ceresin and carnauba wax, plus cetearyl alcohol, a film-forming copolymer, diisostearyl malate and carbon black.
Who it suits (and who should skip it)
Good pick if
- You want a natural, defined lash line rather than a bold wing
- Your eyeliner usually smudges by the afternoon
- You have hooded or monolid eyes and want thin, precise lines
Skip it if
- You want dramatic, thick or winged liner; a liquid liner is easier
- You dislike retractable pencils that can’t be sharpened
- Your eyes are very sensitive to long-wear formulas
What the ingredients do
The pigments give the colour. Trimethylsiloxysilicate is the key to long wear: it forms a flexible, water-resistant film once the volatile silicones evaporate. That’s why the liner glides on creamy and then sets so it doesn’t move.
The waxes give the pencil its body, so the fine tip doesn’t break easily. With few ingredients and no fragrance listed, the formula is simple for an eye product.
How to use it
CLIO’s direction is to draw along the lash line, filling in the spaces between the lashes. Wind up only a little of the pencil at a time, because the fine tip can snap if it’s extended too far.
Work in short strokes, then let it set for a few seconds before blinking. Remove it at night with an oil-based or dual-phase remover, holding a soaked pad on the eye for a few seconds before wiping.
How it compares
CLIO Kill Lash Superproof Mascara is the matching long-wear mascara from the same brand. rom&nd Han All Brow Cara is a tinted brow mascara if you want to finish the eye look.
Is it worth buying in Seoul?
Yes, it’s inexpensive and easy to find in Seoul. We don’t show an Amazon comparison, because the listings we found are different sizes or packs. Olive Young’s price is low, and the double pack is better value. A single pencil is well below the ₩15,000 tax refund minimum, so add it to a bigger basket.
It’s a tiny pencil, so it fits anywhere in hand luggage.
FAQ
Is it really waterproof?
The formula uses a silicone resin (trimethylsiloxysilicate) and volatile silicones that set into a water-resistant film, which is why it holds up well. Remove it with an oil-based or dual-phase eye remover.
Why is it so small?
The pencil is ultra-thin (0.14g of product) so it can draw very fine lines close to the lashes. The trade-off is that it runs out faster than a standard pencil.
Can I use it on the waterline?
Many people use it for tightlining. Keep the tip clean, avoid sharing it, and stop if your eyes water or sting.
Which shade should I buy?
Black (01) is the classic. Brown shades give a softer look. Olive Young often sells a double pack.
