Idea of Sand Clock Icon
Imagine the top shape of a wine glass without the stand and base, and now imagine another one that is upside down and they're both connected. Both of the openings of the whine glasses are enclosed from the top and bottom. There is space in the middle for small objects to pass through.
This is a Sand Clock 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 13,900 icons, all in the same style and quality.
