Lash cluster trays come in very different sizes, from small boxes to sets with several hundred clusters. Before you pick one, it helps to know how many clusters one full set actually uses, and how many sets a tray will give you. This guide does the math for our 280 and 640 piece sets, so you can choose the right first box.
Full disclosure: Pilamie sells both sets below, without glue. The counting method works for clusters from any brand.
How many lash clusters for one full set?
Most people use 5 to 8 clusters per eye, so 10 to 16 clusters for both eyes. A soft, natural look on smaller eyes can need only 4 or 5 per eye. A wide, dramatic cat eye can take 8 to 10 per eye. Cluster width differs by brand, so lay a few along your lash line before you add bond and check they sit side by side from the inner to the outer corner.
Our lash clusters guide for beginners has a simple first map if you have never placed clusters before.
How many sets does a tray give you?
Here is the rough math, before any reuse. Clusters can often be cleaned and worn again a few times, which stretches each tray further.
| 280 piece tray | 640 piece set | |
|---|---|---|
| Full sets at 16 clusters each | about 17 | about 40 |
| Full sets at 10 clusters each | about 28 | about 64 |
| Price | $12.99 | $16.99 |
| Rough cost per full set | about $0.46 to $0.76 | about $0.27 to $0.42 |
Either way, one application costs well under a dollar in lashes. Your bond and remover are the other running cost, since they are sold separately.
280 vs 640: what is the difference?
| 280 piece tray | 640 piece set | |
|---|---|---|
| Clusters | 280 in one tray | 640 in two cases |
| Volume | One volume per tray. Choose 30D, 40D, a 30D + 40D mix, 50D, 60D, 80D or 100D | Four volumes in one set: 30D, 40D, 50D and 60D |
| Curl and length | D curl, mixed 9 to 16 mm | D curl, mixed 9 to 16 mm |
| Best for | Your first box, or restocking the one volume you already love | Trying several volumes, or mixing light and full clusters in one set |
Pick the 280 piece tray if
- You are new to clusters and want a smaller, cheaper first box.
- You already know your volume. The 30D + 40D mix is a good first choice if you are unsure: lighter clusters are more forgiving while you learn placement.
- You want the fullest looks. Only the 280 tray comes in 80D and 100D.
Pick the 640 piece set if
- You already do your own lashes and go through clusters quickly.
- You like mixing: light 30D or 40D at the inner corner, fuller 50D or 60D at the outer corner for a wispy cat eye.
- You want the lowest cost per application.
What do 30D, 50D and 100D mean?
The number before the D shows how dense each cluster is. A higher number means more fibers in each cluster, so the result looks fuller and darker. 30D and 40D sit closer to a natural lash line. 50D and 60D give fuller everyday volume. 80D and 100D are the densest, for a dramatic look. For more detail on volume, curl and length, see how to choose lash clusters.
Want textured, spiky looks instead?
If you already apply clusters and want more texture, the mixed style two tray set combines fuller base clusters with spiky, wispy ones, in four styles. It is not sold by piece count, so choose it for the look rather than the number of sets.
What else you need
Our clusters are sold without adhesive. You will also need a bond made for lash clusters (regular strip lash glue is a different product), a sealant if your bond system uses one, tweezers or an applicator, and a remover that matches your bond. Always patch test a new adhesive first. A heated eyelash curler helps clusters blend with straight natural lashes.
Quick answers
Can I mix volumes in one set?
Yes. Many people put lighter clusters at the inner corner and fuller ones toward the outer corner. The 640 set has four volumes side by side for exactly that.
How long does one application last?
Usually a few days, depending on your bond and aftercare. See how long lash clusters last for tips.
Is buying two trays worth it?
If you have found your volume, restocking the same tray is the cheapest way to keep going. Check the bar at the top of our site for any current multi-buy offer.
