【Note】Perfectionists please purchase with caution. Each keycap is hand-assembled, and the connection between the keycap and the switch is glued with a special adhesive. Some keycaps may have slight glue residue on their surface, but it will not be noticeable. These keycaps are an excellent decoration for mechanical keyboards and are affordable. <br>【One Keycap Included】The package includes: 1 crystal ball keycap and 1 keycap puller. Other keycaps are for display purposes only and are not included. <br>【R4 Area】It is recommended to install the keycap in the R4 area. It is not recommended to install it in frequently used typing areas to avoid affecting keyboard use. You can choose other positions within the R4 area, such as the ESC key. <br>【Easy Installation】Simply pull out the keycap you want; no keycap puller is needed. Then carefully install our keycap. Because the keycap is not molded in one piece but is glued together with a special adhesive, the keycap may be damaged if it is dropped forcefully or forcibly pulled off the keyboard while assembling it with the switch. <br>【Compatibility】Only applicable to mechanical keyboards with cross-shaped switches using the "+" shape, such as Cherry MX, Kailh, Outemu, Gateron, etc.
