Frequently asked questions
Are these full-cover tips or half-cover tips?
Nineteen of the twenty boxes are half-cover extension tips: a clear tip with a C-curve base that is bonded to the free-edge half of the nail and then built over with gel, acrylic or hard gel, so the tip supplies length and shape and the build supplies strength. The one exception is the Long Coffin Matte box, a full-cover soft gel tip that is the whole nail, bonded with gel and cured. For full-cover tips as a range, see Lavis Soft Gel Tips and LDS Soft Gel Nail Tips.
What do I bond and build the tips with?
Bond with a tip adhesive or a bead of builder gel in the well, pressed from the free edge back so no air is trapped. Build over the tip with acrylic (our dip/acrylic powder picked up with monomer), a builder gel from the Lavis bottle or jar, or poly gel, placing the apex over the seam where the tip meets the natural nail. Lavis rates the tips for gel, acrylic and dip systems. The clear tip disappears under the build, so the finished nail reads as one piece.
How many tips are in a box, and how are they sorted?
About 240 tips in the short almond and short coffin boxes, 360 to 550 in the XL, XXL and XXXL boxes, sorted by size in a reusable storage box with one shape and one length per box. Keep tips in the box they came in and refill a size from a second box rather than mixing shapes in one tray; the middle sizes run out first in most salons, so note which sizes went low before you reorder.
Which length should a salon start with?
XL. It is the length most clients picture when they ask for an extension, and the XL almond, XL coffin and XL square boxes cover most requests between them. Add the short boxes for clients who want shape without length, the XXL and XXXL coffin and square for a long-nail clientele, and the duck box if the flared shape is being asked for, since it cannot be filed out of a straight tip.
What kind of tips are these?
Half-cover extension tips: a clear plastic tip with a C-curve base that sits on the free-edge half of the natural nail, is bonded, and then has the rest of the nail built over it in gel, acrylic or hard gel. The tip gives the length and the shape; the product you build with gives the strength and blends the seam. They come pre-shaped, so filing is limited to blending the well and trimming the length, and they are clear so you can see the placement and any gap under the tip.
Lavis packs them the way a salon buys them: about 240 to 550 tips per box, sorted by size in a reusable storage box, one shape and one length per box. This is the tech's tip range. For a full-cover tip that is the whole nail in itself, bonded with gel and soaked off at the end, see Lavis Soft Gel Tips and LDS Soft Gel Nail Tips; one box on this page, the long coffin matte, is that type.
The boxes, by shape
| Shape | Lengths and boxes | Notes |
|---|---|---|
| Stiletto | XL (500), XXL (500) | Clear. The pointed extension; XXL for the longest sets. |
| Almond | Short (240), XL (504), XXL (504) | Clear. The rounded-point shape most clients ask for by name. |
| Square | XL tapered curve (500), XL curved (500), XL tapered no curve (500), XXL no curve (500), XXXL no curve (360) | Clear. "Curve" and "no curve" in the box name describe the tip's profile across the width; tapered narrows toward the free edge. |
| French square | XL clear (550), XL natural (550) | The squared French shape; the natural box for a tip that reads as the nail bed. |
| Coffin | Short (240), short matte (504 and 500), XL no curve (500), XXL no curve (500), XXXL no curve (420) | Clear or matte. Matte takes color without a primer coat showing through. |
| Coffin, full-cover | Long matte (504, 12 sizes) | The one full-cover soft gel box on this page: prep, bond, press, cure, refine. |
| Duck | XL (500) | Clear. Flares out at the free edge; the shape needs a tip, since it cannot be filed out of a straight one. |
Half-cover tip, full-cover tip or dual form?
| Half-cover tip (this page) | Full-cover soft gel tip | Dual form | |
|---|---|---|---|
| What it is | Clear tip on the free-edge half; nail built over it | Whole-nail tip bonded with gel | Reusable mold filled with gel and pressed on |
| Strength from | The gel, acrylic or hard gel built over the tip | The tip itself plus the bond | The cured gel inside the form |
| Skill | Medium: blend the seam, build a structure | Low: size, bond, cure | Low to medium: fill, press, cure, refine |
| Speed | Slower than full-cover, faster than sculpting on a paper form | Fastest full set | Fast once the fit is right |
| Best for | Acrylic and hard gel salons, custom length and shape | Gel salons and home users | Poly gel and builder gel extensions |
How do you apply a half-cover tip?
- Size it. The tip should sit sidewall to sidewall with no gap and no overhang. Between sizes, take the larger one and file the sides after it is bonded.
- Prep. Push back, buff the shine off the free-edge half of the nail where the well will sit, dust and dehydrate.
- Bond. A thin line of tip adhesive or a bead of gel in the well, press from the free edge back toward the cuticle so no air is trapped, and hold or flash cure. A soft gel tip adhesive is the everyday bond; a builder gel bond is cured under the lamp.
- Trim and blend. Cut the length if wanted, then file the well edge flush with the natural nail so there is no step. A fine bit on a nail drill makes this the quickest step; a hand file works.
- Build over it. Acrylic from dip/acrylic powder with monomer, or a builder gel from the bottle or the jar, over the whole nail with the apex placed over the seam. The clear tip disappears under the build.
- Shape, finish, color. File the final shape, buff, then color and top from Base & Top Gel.
Which shape and length to stock
- A general salon: XL almond, XL coffin and XL square cover most requests; short coffin and short almond for the client who wants length without the drama.
- A long-nail clientele: the XXL and XXXL coffin and square boxes, plus XXL stiletto. Build these with the apex further back so the length does not lever the tip off.
- French work: the French square boxes; the natural version reads as the nail bed under a white free edge.
- Trend shapes: the duck box, which flares at the edge and cannot be filed from a straight tip.
- Matte or clear: matte for a tip that will be colored; clear when you want to see the seam and the bond as you work.

Stocking and care
- The box is the storage. Tips are sorted by size in a reusable box; keep them in it, and refill a size from a second box rather than mixing shapes in one tray.
- Buy by the size that runs out. The middle sizes empty first. A box that is out of them still has the ends; note which sizes ran low before reordering.
- Bond matters more than the tip. A tip that lifts was bonded over shine or oil, or with air in the well. Prep the well area the same as you would for gel.
- Dust: blending a plastic tip makes fine dust; a dust brush and a mask from Nail Tools & Accessories.
