Apple yesterday upgraded engraving options for AirPods cases. Customers can now engrave emojis on their devices.

‌AirPods‌ have always been able to be engraved, but the engravings were limited to text. Apple has now expanded the option to include 31 emoji characters. In a Twitter post yesterday, Mac Rumors noted that Apple is now highlighting the new and improved engraving option on its main site and when customers visit one of the ‌AirPods‌ product pages.

While customers still have the option to engrave text, this update, however, doesn't allow both text and emojis to be engraved together. Apple has also tweaked the text that can be added to the ‌AirPods‌, bumping up the size.

The customization is offered for free upon purchase. You can now buy AirPods cases and customize them on Apple's online store.
