The clean, supreme look for your keyboard.
Jezail Funder Japan began offering the LAK Unmarked Keycap Set as a new keycap set on September 22, 2025.
Since it is unmarked, it offers a high degree of layout flexibility and can be used as a replacement keycap for Lofree Flow Lite JIS depending on the combination with other keycaps.
This article will review the LAK unmarked keycap set.

Jezail Funder LAK Unmarked Keycap Set Overview
The LAK unmarked keycap set consists of the following two types
LAK Unmarked Key Caps
- 75s Kit-4,180 yen (tax included)
- Space Kit-1,540 yen (tax included)
The 75s Kit is compatible with low-profile mechanical keyboards with ANSI layouts below the typical 80% TKL.
The most famous low-profile mechanical keyboards with ANSI layout are Lofree and NuPhy.
KawamuraFlow/Flow2 as well as the NuPhy Air series, Kick75, NOS75, etc. may be used.
As for the Space Kit, it contains Convex keys of various sizes and is ideal for low-profile Alice layout keyboards such as the Keychron K11 MAX and K15MAX, or for those who want to build their own keyboards in the LAK profile.
Also, by purchasing at the same time as the LAK key cap color (100 yen (tax included)/piece), you can add an extra color.
In addition, when combined with the separately sold “LAK Keycap Non-Imprinted (100 yen (tax included)/piece)”, which is sold separately, it can be used with most ANSI keyboards and special sequence keyboards.
KawamuraHowever, Air75v3 JIS cannot replace the space bar only because the space bar is 4.25u.
However, Flow Lite JIS can completely replace it by purchasing ISO Enter and Space Kit.
[Photos] Jezail Funder LAK Unmarked Keycap Set Review
Let’s take a look at the Jezail Funder LAK unmarked keycap set.
We were provided a sample of a single keycap (1u size) for accents and a single ISO Enter in addition to the 75s Kit/Space Kit.
It comes in a special plastic tray with the brand logo.
It is a well-known saying in Japan that “white has 200 colors,” but the white used at LAK is a “pure blue-ish white” with a high color temperature.
KawamuraIt is difficult to describe, but it is white in a different direction from ivory.
This tray contains keycaps of various mod key sizes.
KawamuraThis time it arrived as a set, but there are probably two trays for the 75s Kit alone.
The last tray contains the Space Kit and single keycaps.
LAK keycaps currently sold individually come in three colors: yellow-green, blue, and orange.
The colors are very crisp.
As for ISO Enter, it was vacuum packed separately.
Let’s look at the shape of the keycap.
LAK keycaps are characterized by the “cylindrical” shape of the keycaps, which are horizontal cylinders like this one, with the key tops cut out in an arched shape.
There is no difference in vertical slant from row to row.
You can see that even the ISO Enter, which has the widest top surface, has a slight cylindrical shape.
On the other hand, the space bar included in the Space Kit has a convex shape.
A comparison photo is below.
KawamuraWhen you put them side by side like this, they are quite distinct.
Similarly, compare with Lofree’s low-profile keycaps adopted from Flow2, which have a cylindrical shape and no difference in slope from row to row.
As for the top surface area, Lofree in its normal shape is larger.
On the other hand, the LAK profile, which looks like a smaller keycap on a square base, has a narrower top surface.
KawamuraSurprisingly, I had the impression that a narrower top surface area would capture the keys more accurately.
Viewed from the side, the Flow2 keycap appears to have a slightly stronger arched arch.
Let’s actually attach it to the keyboard.
We will start by looking at Flow2 as a comparison.
In this case, only the arrow key is replaced, but all of them can be replaced.
Although the area of the top surface is different, it is the same cylindrical shape, so there is no discrepancy at all if it is only replaced as an accent.
We then replaced the ESC key on the NuPhy Air75v3 JIS.
This one may be slightly uncomfortable to use in combination with the original keycap because of its spherical shape (depressed toward the center).
KawamuraIt is not so noticeable when replaced as an accent like this.
Air75v3 JIS can replace all but the space bar.
All normal Air75 ANSI layouts can be replaced.
Finally, let’s replace Lofree Flow LITE JIS.
Flow LITE JIS can replace all 75s Kit and Space Kit in combination because the space bar is 2u/2.25u size.
If we replace everything, it will look like this.
It looks quite refreshing.
The default keycap has a spherical shape, but the LAK keycap has a cylindrical shape, so it looks like Flow2.
The uniform bow shape is beautiful.
The space bar also has a solid convex shape (raised) when viewed this way.
Also, adding an accent keycap changes the impression considerably.
KawamuraPersonally, I found the orange accent keycaps to be quite on point, so I took more photos of the orange keycaps.
Summary｜LAK profile keycaps are recommended for Cherry profile lovers.
This is our review of the Jezail Funder LAK profile keycap unmarked series.
The fact that it is unmarked means that it is definitely a product for experts, but if it can be turned into such a clean looking keyboard, there is no harm in buying it to try it out.
KawamuraOnly the alpha key can be changed to an engraved key by combining it with the LAK keycap with engraving, which is sold separately.
However, please note that the printing is only in English alignment.
Many low-profile mechanical keyboards with ANSI layouts can replace all keys.
Why don’t you give it a try too?
