A cucumber is a straight line that slowly curves inward to make it end to a point but with a rounded edge that goes back around and curves. So it's both sides a straight line with a slight curve outward that is slightly rugged in nature. They curve back to meet on the other hand with small bumps all over it.
This is a Cucumber 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 13,300 icons, all in the same style and quality.
