TVL Cluster Guide: Length, Curl & Density Explained

Every TVL Cosmetics cluster tray is designed to a precise specification — length, curl, and density — so you always know exactly what you're applying. This guide breaks down what those numbers and letters mean and shows you which tray to reach for based on the look you want.


📏 Length — What the Millimeter Range Means

TVL trays contain multiple lengths within a single tray, giving you variety without buying multiple kits. Lengths are measured from the lash band to the tip of the longest fiber.

Tray Length Range What That Looks Like
3-in-1 Cluster Kit 14 mm – 20 mm Medium-to-long. The shorter clusters (14–16 mm) anchor the inner corners; the longer spikes (18–20 mm) create the wispy, lifted outer-corner effect. Best for dramatic, editorial looks.
Full-Coverage Clusters 10 mm – 18 mm Short-to-medium. A wider spread of lengths for seamless blending across the lash line. One layer delivers full coverage. Versatile from natural to glam.

How to choose by length: If you want a dramatic, longer finish — reach for the 3-in-1 Kit. If you prefer a more buildable, blended look starting from a shorter base — Full-Coverage is your tray.


🌀 Curl — C-Curl vs. D-Curl

Curl describes the arc shape of the lash fiber from base to tip. TVL uses two curl types across its trays.

Curl Shape Best For TVL Tray
C-Curl Moderate upward sweep — follows the natural curve of most lash lines Everyday wear, open-eye effect, beginners, hooded or monolid eye shapes Full-Coverage Clusters (80D C-Curl)
D-Curl More dramatic upward lift — a tighter, more pronounced curl Lifted, wide-awake look, layered sets, dramatic styling, downturned eye shapes 3-in-1 Cluster Kit (100D D-Curl)

Tip: You can layer a D-Curl over a C-Curl base for a customized lift. Pair the Full-Coverage tray as your base coat, then accent with 3-in-1 spikes on the outer corners.


💎 Density — What 80D and 100D Mean

TVL uses a D-number (Density number) to describe how many individual fibers are bonded into each cluster. This is TVL's internal specification — it is not a universal industry standard and should not be compared to other brands' density labeling.

Density Label Fiber Count per Cluster Resulting Look TVL Tray
80D ~80 fibers per cluster Fluffy, full, dark — one layer achieves complete lash-line coverage. Natural-to-glam range. Excellent for beginners. Full-Coverage Clusters
100D ~100 fibers per cluster Bolder volume, deeper darkness. Designed for layered, dramatic sets. The extra density reads as more intense even before styling. 3-in-1 Cluster Kit

Both trays use the same lightweight, comfortable construction — neither will feel heavy on your lash line when applied correctly with TVL Bond & Seal.
