It is made from resin and follows the default OEM R4 height, which is the same height as the ESC key. The design is available in Black, Blue, Green, Pink, Purple, and Red, so you can choose a colour that fits your keyboard theme or stands out as a single accent. It is important to note that this model is not compatible with Omron axis, Razer optical axis, or odd-shaped axis keyboards. Before buying, check your switch type and keycap profile to confirm that the keycap will fit as intended.\u003c\/p\u003e\u003ch2\u003eFeatures and Construction\u003c\/h2\u003e\u003cdiv style=\"text-align: center;\"\u003e\u003cimg alt=\"Koi resin mechanical keyboard keycap for MX cross axis switches, OEM R4 ESC height, available in six colours.\" src=\"https:\/\/images.seoo.uk\/src\/products\/shopify_export\/US14\/2923\/2025-10-16\/original-image\/1305829104410.webp\"\u003e\u003c\/div\u003e\u003cp\u003eThe keycap is built around a resin body with a koi design and is intended for MX cross axis switches. Its OEM R4 height gives it a defined place in a standard keycap row, most commonly the Escape position. The available colour range makes it easy to coordinate with an existing keyboard or to add one distinct key.\u003c\/p\u003e\u003ch3\u003eMaterial and Build\u003c\/h3\u003e\u003cp\u003eThe keycap is made from resin. In use, resin provides a solid moulded shape for the koi design and the keycap structure, without adding flexible or soft components. The source information does not include additional durability, coating, or performance claims, so the keycap should be treated as a decorative resin accessory for compatible mechanical keyboards. It is designed for MX cross axis switches and should not be forced onto incompatible switch types.\u003c\/p\u003e\u003ch3\u003eSize and Practical Fit\u003c\/h3\u003e\u003cp\u003eThe default OEM R4 height is the ESC height. This means the keycap is intended to sit in the Escape row position on a keyboard that uses OEM R4 profile keycaps. No other dimensions or weight measurements are provided. If your keyboard uses a different row profile or a non-standard layout, check the fit before ordering. The keycap is not suitable for Omron axis, Razer optical axis, or odd-shaped axis keyboards.\u003c\/p\u003e\u003ch2\u003eUses and Placement\u003c\/h2\u003e\u003cdiv style=\"text-align: center;\"\u003e\u003cimg alt=\"Koi resin mechanical keyboard keycap for MX cross axis switches, OEM R4 ESC height, available in six colours.\" src=\"https:\/\/images.seoo.uk\/src\/products\/shopify_export\/US14\/2923\/2025-10-16\/original-image\/177358863717.webp\"\u003e\u003c\/div\u003e\u003cp\u003eThis keycap is suited to mechanical keyboard users who want a single decorative key rather than a full set. It can be used on the Escape position or another compatible OEM R4 location, depending on your keyboard layout. The koi design and colour options make it a visual accent for a personalised setup.\u003c\/p\u003e\u003ch3\u003eEvent or Professional Use\u003c\/h3\u003e\u003cp\u003eFor gaming or office keyboards with MX cross axis switches, this keycap can replace a standard Escape key with a koi-themed design. It is not a functional upgrade for switch performance and does not change the typing feel beyond the keycap itself. Its practical role is visual identification and customisation. Confirm that your keyboard uses MX cross axis switches and that the target position accepts OEM R4 height before fitting.\u003c\/p\u003e\u003ch3\u003eEveryday Home Use\u003c\/h3\u003e\u003cp\u003eAt home, this resin keycap can be used to add a colour accent to a mechanical keyboard. The six colour options are Black, Blue, Green, Pink, Purple, and Red, so it can match a wide range of desk setups. Because only one keycap type is described, it is best suited to a single accent position rather than replacing a full row. Keep it away from incompatible switch types and avoid forcing it onto non-MX cross axis mounts.\u003c\/p\u003e\u003ch2\u003eBenefits and Buying Value\u003c\/h2\u003e\u003cdiv style=\"text-align: center;\"\u003e\u003cimg alt=\"Koi resin mechanical keyboard keycap for MX cross axis switches, OEM R4 ESC height, available in six colours.\" src=\"https:\/\/images.seoo.uk\/src\/products\/shopify_export\/US14\/2923\/2025-10-16\/original-image\/3761140127677.webp\"\u003e\u003c\/div\u003e\u003cp\u003eThe main value of this keycap is its combination of a koi resin design, MX cross axis compatibility, OEM R4 ESC height, and a choice of six colours. It offers a straightforward way to change the look of one key without buying a full keycap set. The limits of the known data are clear: no extra measurements, pack quantities, or performance ratings are provided.\u003c\/p\u003e\u003ch3\u003eReuse and Low Maintenance\u003c\/h3\u003e\u003cp\u003eAs a resin keycap, it can be removed and refitted when you change compatible keyboards or reposition your accent key. No specific cleaning or maintenance instructions are provided in the source, so keep care minimal and avoid harsh chemicals. If dust builds up, a soft dry cloth is a low-risk option for general surface cleaning. Do not use abrasives that could affect the resin surface.\u003c\/p\u003e\u003ch3\u003eWhy Choose This Product\u003c\/h3\u003e\u003cp\u003eChoose this keycap if you have an MX cross axis mechanical keyboard and want a koi design in a specific colour.
