Lash Tech Supply List for 2027: What to Stock and How Much

This is the full list in one table. The sections below explain each line.

The studio basics in the last row are one-time or bulk purchases that are not covered in this list. Everything above that row is something you will reorder, so those are the lines to plan for 2027.

Lash trays are the biggest line on the list and the easiest to overbuy. Start narrow and let your appointments tell you what to add.

• Volume: 0.05 mm in C or CC curl, Mix 8–16 mm, is a versatile first tray. Add 0.07 mm for hybrid details and 0.03 mm if you offer mega volume.
• Classic: 0.15 mm in C or CC curl, Mix 8–16 mm, suits healthy natural lashes. Add 0.10 mm for fine lashes.
• Special curl: one L or LC tray for hooded eyes and straight or downward-growing lashes.
• Finish: Matte Black for a softer black, Ultra Black for a deeper, more defined lash line. See Matte Black vs Ultra Black.
• Single lengths: add these after a few weeks, for the lengths that run out first on your mixed trays.

All COMELYLASH trays have 16 rows of PBT fibers, and lash curl is stable for up to 12 months when trays are stored correctly. That makes trays the one supply you can safely buy for the whole year. For every diameter, curl and length we stock, use the Lash Extension Size Chart.

Choose adhesive by two things: how fast you work and what your room is like. Both of our adhesives come in a fast and a slower speed.

• If your room changes with the seasons, the All-Climate adhesive has the wider working range.
• If your room is climate-controlled and you want a low-odor adhesive, Power Bond is made for that steady environment.
• If you are still building speed, start with the slower option (0.5s or 1s) and move to a faster one later.

Adhesive is the supply to buy little and often. Power Bond, for example, has an unopened shelf life of 6 months and should be used within 3 months of opening. A bottle that sits in a drawer for half a year is not a saving.

These two liquids sit on either side of the set, and you need both.

• Eyelash Primer GP1 (before): applied to the natural lashes before extensions. Let it dry before you start.
• Super Bonder GB1 (after): applied to the bonding points once the set is complete. It helps the adhesive cure in about 3 minutes and reduces odor release. It is alcohol-free.

Both are 10 ml bottles with a shelf life of 12 months unopened and 6 months after opening. For one studio, one bottle of each at a time is usually enough; open the next one when the first runs low or reaches six months. For the full comparison, read Lash Primer vs Super Bonder.

Tweezers are a one-time purchase that lasts, so this is where it pays to choose carefully rather than cheaply.

• Isolation: one pair to separate the natural lash, held in your non-dominant hand.
• Pickup and placement: one pair for your technique: a classic pair for single lashes, a volume pair for making fans.
• Fiber tip or not: a fiber tip adds grip when picking up fine fibers. Our Black-Gold and Titanium Black tweezers come in both fiber tip and non-fiber versions, so you can compare.
• A spare: keep a second pickup pair, so a dropped tweezer does not stop a full set.

Our lash tweezers guide explains each shape and what it is for. If you are building a brand, tweezers can be engraved with your logo.

These are small line items, but you use them on every client, so running out stops work just as fast as running out of lashes.

• Lash tape: keep one everyday tape and one gentler option for clients with sensitive skin. We stock PE, Japanese, non-woven and silicone tape; PE vs Japanese vs Non-Woven vs Silicone Lash Tape compares them.
• Glue rings: our disposable glue rings come 100 to a bag, with a dual-well cup, and are designed for single-client use. Count one per client, plus a few for refills of fresh adhesive during long sets.

Count your weekly appointments and multiply. If you see 15 clients a week, a bag of 100 glue rings lasts roughly six weeks. Do the same sum for tape and reorder when you reach the last two weeks of stock.

Aftercare is the part of the list that can pay for itself: you sell it at the appointment, and cleaning and protecting the lashes at home supports retention between fills.

• Whipped Lash Shampoo: a whipped foam cleanser, 100 ml per bottle, unscented or strawberry. Sold as 1 or 50 bottles, with a blank or COMELYLASH label.
• Lash Protective Coating: a clear, water- and oil-resistant coating that helps protect the bonding points.
• Lash Styling Coating: a daily coating that helps keep the lashes neat and shaped.
• How clients use the coatings: wait at least 2 hours after the appointment, then apply a small amount to the bonding area 2–3 times a day.

The simplest way to plan a year of supplies is to sort them by how long they keep. These figures come from our product pages:

For other products, including All-Climate Lash Adhesive, check the label on the bottle you receive.

• Write the opening date on every bottle of adhesive and liquid the day you open it.
• Use the oldest bottle first, so new stock does not get opened before the old one is finished.
• Keep client records of the sizes you use per zone. Our free Lash Map Generator builds a lash map you can print or save to the client card, and your records show which trays to reorder.
