These markings are known as sprue marks. This is normal and is necessary for injection moulded products.

DailyClack, as a vendor, places many orders with a wide range of different keycap manufacturers located at many different locations.

For reference:

• CRP Hammerworks - China
• Keyrelative - China
• Signature Plastics - United States of America
• Uniqey GMK - Germany

Each manufacturer will have their own production process and procedures; DailyClack has little-to-no control over how these businesses operate. DailyClack simply ships what is ordered and produced.

As keycaps are made from a technique known as injection-molding, Sprue Marks are hard to avoid. These marks are the locations where the liquid-plastic gets “pushed” into a keycap mold.

Once installed onto a keyboard and viewed at a normal typing distance, these markings are not visible and don't effect usability.

Different manufacturers have different techniques, so the location of these marks will vary.
