BTArtbox XCOATTIPS White French Coffin
Pre-built white French coffin extensions — salon shape without the salon build.
Shop on AmazonSearch for french nail tips and the results are three different products wearing one name. Some are the thin white crescents a salon glues to the end of your nail before building acrylic over them. Some are full-length clear soft-gel nails you glue on whole and paint. And some are full-cover nails with the French line already printed, which are press-ons in everything but the adhesive. They look similar in a thumbnail and behave nothing alike.
The grid above mixes all three on purpose, because people who search the phrase want one of the three and rarely know which. The table sorts it out.
| Type | What it is | You add | Adhesive | Skill | In this grid |
|---|---|---|---|---|---|
| Half-cover tip | A crescent that glues to the free edge | Acrylic or builder gel over the top | Nail glue, then the build | Highest — the build is the manicure | Krofaue, ranrose, Beuniar, FEBSNOW, NOVO OVO half-cover |
| Full-cover blank | A whole clear soft-gel nail | Base, French line, top coat | Gel glue or solid gel, cured | Medium — sizing plus painting | UNA GELLA almonds, Krofaue clear |
| Full-cover pre-painted | A whole soft-gel nail with the French already on | Top coat only | Gel glue, cured (X-Coat lets light through) | Lowest — sizing and prep | BTArtbox X-Coat, Beetles, Gellen, Misssix, Canvalite, NOVO OVO square |
Pre-painted full-cover tips first (the fastest route), then blank soft-gel tips, then the half-cover tips salons build acrylic over. The table below says which is which.

This is what a nail technician means by "tips." The white or clear crescent glues onto the free edge of your natural nail, the join at the well gets filed flush, and then acrylic or builder gel is sculpted over the whole nail — tip and natural plate together — to make one smooth surface. The white tip is the French; the pink or clear build over it is the base. That is why a set of white half-covers costs four dollars for five hundred: the tip is a small piece of ABS plastic, and the manicure is the build.
It is also why half-cover tips are the wrong purchase for anyone without acrylic or builder gel and the skill to use it. A half-cover with nothing built over it is a plastic crescent glued to your nail.
Within the family, the choices are colour and length. White half-covers (Krofaue's 500-piece white, ranrose's short white, Beuniar's classic ABS) give a fixed smile line at a fixed depth — fast, uniform, and not adjustable. Clear and natural half-covers (Krofaue clear, FEBSNOW's thousand-piece box) leave the French for you to paint or cut after the build, which is more work and more control. The NOVO OVO square half-cover splits the difference: a half-cover with the white line already painted, at a price that reflects it.
The newer method. A full-length soft-gel nail — thin at the cuticle edge, thicker at the front, shaped to almond or square or coffin — is glued on whole with gel glue or a solid gel adhesive, cured under a lamp, and finished with a top coat. There is no sculpting. The tip's underside is roughened (the "inner matte" or "frosted" texture every listing mentions) so the adhesive has something to grip.
Two things separate the sets in this family. Pre-primed or not: BTArtbox's X-Coat line ships with primer and base already on the tip and is engineered to pass lamp light through so the gel glue cures underneath — which is what the four-week claim rests on. Everything else needs you to prep the tip. Painted or blank: the X-Coat sets, Beetles' long square, Gellen's and Misssix's soft-gel Frenches and Canvalite's pre-coloured tips arrive with the French line on; UNA GELLA's almonds are clear blanks you paint.
The blanks are the sleeper pick for anyone who can already draw a decent line. You paint the French on the tip before it goes on your hand — flat, steady, at your own pace — then glue and cure. It is the easiest surface you will ever draw a smile line on.
Pre-painted full-cover French tips are the fastest route in the entire shop to a salon-length French: size, prep, glue, cure, top coat. No line to draw. On the BTArtbox X-Coat sets the primer and base are already there too, so the whole job is about fifteen minutes once you know your sizes.
The limit is that the line is fixed. Every tip in the box has the same smile at the same depth, which on most hands looks uniform in a good way and on some looks like a set. If you want a thin French or a deep one, check the product photo for depth before buying — a "deep French" set (Misssix's is labelled that way) and a standard one are different products.
Colour follows the same logic. Most pre-painted sets are white on pink or nude. BTArtbox's brown French almond is the brown French pre-built; NOVO OVO's berry-pink base is the pinker version of the classic.
Every listing in this grid quotes a size count — ten, twelve, fifteen, sixteen — and the number matters more than the price.
A tip that is too narrow leaves a strip of natural nail at the side wall, which on a clear or nude base shows as a shadow and on a white French shows as a line. A tip that is too wide overhangs the side wall, presses into the skin, and lifts within days. Neither is fixable after gluing.
So: measure. Lay each tip across the widest point of the corresponding nail and look for side-wall to side-wall contact with no gap and no overhang. When two sizes are close, take the wider one and file the sides down before gluing — soft gel files cleanly, ABS less so. Photograph the sizes you settle on next to the box's chart. Every subsequent box of the same brand then fits first time, and different brands use different scales, which is why a "medium" from one is a "small" from another.
Fifteen- and sixteen-size sets (BTArtbox, Beetles, Gellen, Misssix, NOVO OVO) fit more hands than ten-size sets (Beuniar, FEBSNOW), because the extra sizes sit at the ends of the range — the wide thumbs and narrow pinkies that ten-size boxes miss.
The most common failure on full-covers is curing with the finger moving. Gel glue takes a few seconds to set under the lamp, and any shift in that window leaves an air pocket at the cuticle edge that lifts within the week.
Tips get blamed for damage that removal did. File the top coat off, soak in acetone with a cotton pad and foil on each finger — ten to fifteen minutes for soft gel, twenty or more for acrylic — and lift only when the adhesive has gone soft. If it resists, soak longer. Prying a cured tip off takes the top layers of your natural nail with it, and that thinning is the "damage" that gets attributed to extensions.
For everything upstream of the tip — the white to paint on a blank, the brush to paint it with, the chrome to finish it — the rest of the shop is one click away: white gel polish, liner brushes, chrome powder, and the French tip cutters that give a built nail a perfect line. If you would rather not build at all, press-on French tip nails are the finished version. For the shapes these tips make, see coffin, almond and square French tips, and for the question of acrylic versus gel over the top, French tip acrylic vs gel.
