As I mentioned in my most previous Jadilla J postVOV's other princessy line Castledew has one of those slim liners out so I decided to order it...and because ordering one eyeliner is boring and each liner came with a freebie I decided to get the other regular pencil, too =)
As I had expected the Castledew Pen Eyeliner is nearly identical to Jadilla J's Eyepen Technic Liner. Even the pen design is very similar. Both have a pink rhinestone attached to the cap and both have a very fine slim tip to draw a fine very even line. I love both and both cost me the same so they're pretty much interchangeable. This is definitely one of the best liners I own as those super slim flexible feltpen-type liners work best for me.
It stays on all day long without smudging and can be a bit hard to remove if you layer it several times (just like all other liners like this)
I paid 9900 Won and got a free eyeliner. (this one is pretty useless as it's a bright pink eyeliner =X)
The other pen I got is the Lineshot Pencil, a regular automatic pencil in a twist-out sort of pen. The interesting thing about this is that this is dual-ended but both sides are the very same color (black). So this means you have 1 refill in your pencil so you get double the life-time out of it compared to regular automatic eyeliners.
The liner is very pointy at first so you need to use it a bit to blur the tip a little. After that it really works nicely and comes out as a very dark black on me. It's quite pigmented and glides on nicely. Staying power is great, too! Note: I only use this pencil on my lower lids as I never use pencil liners on my upper lids... only liquids, gels and those felt-pen like liners. I paid 8900 Won and got a free Eye Smoothie in white (a very shimmery white cream shadow)
