How has one of Japan’s most popular low-profile keycap sets evolved in its v2 iteration?
The Jezail Funder LAK v2 keycaps are the second version of LAK, a proprietary profile developed by Jezail Funder.
They retain the cylindrical top, with no change in slope from row to row.
The biggest change is that transparent materials can now be used.
This article focuses on the differences between v1 and v2.

What Are Jezail Funder LAK Keycaps?

LAK keycaps are low-profile keycaps developed by Jezail Funder.
They have no change in slope from row to row, and their keycap tops are curved (cylindrical).
The center also sits raised relative to the keycap’s outer edge, and the top surface is deliberately shaped to be smaller—a distinctive feature.
Our impression is that the deliberately smaller top surface is intended to make it easier to recognize the position of your fingertips.
What Is LAK v2?
LAK v2 is a successor model based on LAK v1, with a redesigned mold.
It was first used in the “White” model, released to mark the first anniversary of the Cornix LP.
After it was announced in August 2026, the first release was a blank model.
The only official information is that “the keycaps are slightly taller than in v1”; no explanation has been given for the move to v2.
Our Thoughts on Why LAK v2 Was Developed
This is purely speculation, but I think LAK was updated to v2 to make it possible to mold the keycaps from PC.
In recent years, “skeleton” and “half-skeleton” designs have become a trend in Japan’s keyboard scene, and I feel they’re popular because they look good.
Looking at Jezail Funder Japan’s lineup, the LCK profile is available in both transparent and non-transparent models.
LAK, on the other hand, has only been available in PBT—in other words, in non-transparent models.
Perhaps the existing mold either “wasn’t suitable for transparent materials” or “didn’t work well when molding with transparent materials.”
KawamuraThis is all speculation.
Personally, I see LAK more often than LCK in the custom keyboard scene, so perhaps people were asking for a transparent LAK, just like LCK.
LAK v2 Keycaps in Photos: A Comparison with LAK v1
Let’s take a look at LAK v2 alongside LAK v1.
Unless otherwise noted, LAK v2 is on the left and LAK v1 is on the right.
The difference is very slight, but LAK v2 appears to have a somewhat wider top surface.

The bumps on the homing keys seem a little shallower, but not enough to affect the feel in use.

LAK v2 appears to be slightly taller.
The convex keys looked the same in this respect, too.


The photo angles and the height when mounted on the switches differ slightly, but LAK v2 is on the left and LAK v1 is on the right.
In this view, the curvature of the top also appears slightly more pronounced on v2.

Left: LAK v2; right: LAK v1
There is almost no visible difference when mixing v2 and v1 keycaps.
KawamuraThe keycap at the upper left is v2; all the others are v1.
V2 feels slightly taller, but it may be impossible to tell the difference when they are mixed.

The look and feel of the transparent LAK keycaps
One major change in v2 is the addition of a model made from a translucent material.
However, the specific material used for the translucent version is not stated.
KawamuraIt is probably PC (polycarbonate).
First, let’s take a look at the clear version.

With clear keycaps, the switch stem’s color shows through.
The stem color of the Kailh Taro Icecream mini really stands out.
The semi-matte finish is excellent.
Next, the black-clear version.
Here, the stem color is much less noticeable.

From the side, you may be able to make out some of the stem and housing colors.

In a slightly dim environment, it looks almost entirely black.


KawamuraAs an aside, the Banana 2 case has a brushed aluminum finish.
Wow, beautiful.


Conclusion
That wraps up our look at the Jezail Funder LAK v2.
Compared with LAK v1, there are no dramatic changes, and I still find it easy to use.
Rather than a change in shape, the key development is that a wider range of colors now seems more likely.
I’m looking forward to seeing what models appear in the future.
Only blank models are currently available, but I’m also looking forward to the release of models with legends.
