At this time, Charlotte Tilbury's 2-in-1 Lip Gloss does not come with a keychain attachment. The product is typically sold in its regular packaging, which consists of a compact tube or wand. However, it's important to note that cosmetics companies often release limited edition or special packaging variations of their products, so it is possible that a Charlotte Tilbury 2-in-1 Lip Gloss with a keychain attachment could be released in the future as part of a promotional campaign or collaboration. It's always a good idea to keep an eye on the brand's official website or social media channels for any updates or announcements regarding new product releases.
