An invite icon consists of an envelope and a piece of paper that is coming out of the envelope. The envelope will be open so the flaps on the top will be lifted up to show the rectangular shape paper. The paper will also have information such as a plus sign on it.
This is a Invite icon. We've made it in iOS style
, first introduced in iOS version 7 and supported in all later releases up until now (at least iOS 11). This style is based on thin two-pixel lines and is optimized for 50x50 px. Unlike other vector icon packs that have merely hundreds of icons, this icon pack contains 13,700 icons, all in the same style and quality.
