KLLX Rod + Tray Cheat Sheet
BKO KLLX Rods & Lash Trays ✦
rod & tray selection cheat sheet for korean lash lift + extensions · bkolashclub.com
Key
KLLX only uses the 3 most natural-curl rods in the BKO lineup — C Curl, Raindrop Curl, and CU Curl
"Sizing rule" = how much bigger to size up from your standard KLL rod choice
"Check" = how far the natural lash should reach up the rod for a seamless attachment point
Trays = the BKO U-Curl Camellia Lash Trays (UC / UB / UJ) — built specifically to blend with a lifted lash base

Why only 3 rods work for KLLX: extensions need a near-seamless attachment point on the natural lash. Too much post-lift curl creates too big a gap between the natural lash and the extension — which means poor attachment and bad retention. The rest of the BKO lineup (LC, L, M, V) is reserved for lift-only services.
₊⊹ rod selection for KLLX
| Rod | Profile | Sizing rule | Best for & why |
|---|---|---|---|
C Curl Rod |
Thin center profile |
Size up 2
Check: natural lash reaches ~50% up the rod
|
Best for standard clients — the most versatile KLLX rod.
Thinner profile means less room to give, so it has to be sized up more aggressively than the others.
|
Raindrop Curl Rod |
Thicker profile |
Size up 1
Check: natural lash reaches ~65% up the rod
|
Best for monolid clients — designed specifically for this eye shape.
Automatically rules out CU and C Curl when the client is monolid.
|
CU Curl Rod |
Very thick profile |
Size up 1
Check: natural lash reaches ~65% up the rod
|
Best for clients with long natural lashes (CU5 is the go-to size) and deep-set eyes.
Thicker profile gives more room to work with for complicated eye shapes.
|
Reminder: the natural lash and extension should meet at a uniform angle, with no more than a 45° gap between them — that's what makes the attachment look like one continuous lash.
₊⊹ lash tray selection for KLLX
the BKO U-Curl Camellia Lash Trays — the only trays built to blend seamlessly with a lifted lash base
| Tray | Curl level | When to use | |
|---|---|---|---|
UC Curl |
Most curled of the 3 | When the post-lift result is more pronounced, or the client prefers a more lifted finish. | |
UB Curl |
Middle of the 3 | The default tray for most clients — a good in-between of super natural and slightly more lifted. | |
UJ Curl |
Flattest of the 3 | When the post-lift result is subtle, or the client wants coverage/darkness rather than lift or length. Also good on the bottom layer for added darkness. | |
Why not standard CC or LC/L-B/C/J trays? Even tilted upward, their curve points back toward the eyelid or brow instead of blending with the permed lash — so the bond looks obvious instead of seamless. UC/UB/UJ are curved to mimic the post-lift lash shape itself, which is what makes the attachment point disappear.
₊⊹ KLLX 01 vs KLLX 02 — which look is right for them?
a preview of the two signature KLLX looks — the full technique breakdown & live demo walkthroughs are in the mini course
look 01 · hyperrealistic
KLLX 01
"your lashes but better"
$175
Best for
Clients whose lash length is already decent and who want subtle enhancement, not a dramatic transformation — previously happy with their lashes but want "more," without the look of obvious extensions.
look 02 · enhanced
KLLX 02
"your lashes but darker"
$195
Best for
Clients with sparse areas or shorter, thinner lashes in specific zones who want density and darkness — not just length. Often clients with naturally light-colored lashes who want fuller lashes without a fake appearance.
Both looks use the same rod & tray logic above — the mini course walks through exactly how to choose between them on a live client, plus the full technique breakdown for each.
