It’s hard to believe that WhatsApp hasn’t had stickers until now, but the messaging app is finally rolling them out. The company announced in a blog post today that the stickers will be coming to iOS and Android in the coming weeks, though some users are reporting that the new update already brings the functionality.

Stickers are accessible through the new sticker icon in the text input field, which will open up a menu of stickers. Like its parent company Facebook’s sticker system, you have to first download the sticker pack you want before you can use it. For now, the stickers are created by WhatsApp designers along with a few selections from other artists. WhatsApp has also added support for third-party sticker apps on Android and iOS, so if you have a sticker pack published to the Google Play Store or App Store, users can send those stickers within WhatsApp. The company has posted a guide to creating stickers for WhatsApp here.
