Until August 27 at 10:00 PM—48 hours from the sales start—the assembled version is available from $99, and the Only KIT from $89.

Purchases made during this period include a dedicated keyboard case.

The ‘Only KIT’ does not include switches or keycaps

On the official sales page, the Only KIT option is listed as follows:

Only Kit (No Switches or Keycaps)

In other words, the Only KIT does not include key switches or keycaps.

Since the Init40 supports hot-swappable Kailh Choc V2 switches, if you choose the Only KIT, you will need to separately prepare compatible key switches and keycaps.

The product page lists the standard contents for the assembled version, including the main unit, dedicated case, USB Type-C cable, 2.4GHz receiver, replacement keycaps, instruction manual, and keyboard strap.

However, the specific breakdown of accessories included with the Only KIT is not explicitly stated.

At minimum, the product selection field confirms that key switches and keycaps are not included.

It’s likely safe to assume the Only KIT contains the same accessories as the assembled kit, minus the keycaps and key switches.

Pricing Varies by Color and Switch

While the announcement images indicated the assembled version starts at $99 and the Only KIT at $89, actual pricing varies depending on color and switch selection.

As of August 26, 2026, pricing is as follows:

ColorOnly KITWhite Rain / Black CloudDeep Sea Linear / Tactile
Black$89$99$101
Silver$89$99$101
White$92$102$104

White is priced $3 higher than Black and Silver.

Additionally, selecting Deep Sea Linear or Deep Sea Tactile for the assembled version adds $2 compared to White Rain and Black Cloud.

It is important to note that the announced prices of ‘$99’ and ‘$89’ are starting prices, and the final cost will vary depending on your choice of color and switches.

Assembled Version Offers Four Kailh Choc V2 Switch Options

You can select from the Deep Sea series, offering smooth linear, tactile with feedback, or silent options prioritizing quiet operation.

If you plan to use it in an office, we recommend the silent switches.

TELEC Certification for Japan in Progress

The sales page includes the following statement:

We are in the process of obtaining TELEC certification.

At this time, TELEC certification for Japan is described as being in progress, not yet obtained.

We await official confirmation of its acquisition.

Greenkeys Has Also Published a Hands-On Review

R0000698

Greenkeys has published a short hands-on review of the Init40 ahead of the sales launch.

Because it adopts a row-staggered layout similar to standard keyboards, it’s an accessible option even for those interested in 40% keyboards but hesitant about ortholinear or columnar staggered layouts.

Summary

888

That covers the sales launch of the Chosfox Init40.

The launch pricing—starting at $99 for the assembled version and $89 for the Only KIT without switches and keycaps—represents highly competitive pricing and is a major draw.

Additionally, this is an in-stock sale rather than a Group Buy (GB), with 300 units already prepared for shipping, which offers the significant advantage of being ready to use shortly after ordering.

Our editorial team considers this an ideal choice for those looking for their first small-form-factor keyboard.
