This typeface, which is expressed in the form of a long body due to the narrow width of the letters, will tidy up your image with a clean and refined look. It has a funny name.
Please check the following before you purchase:
Go to Settings->Display, and check if you see ""Font"" or “Font Style” on the menu.
If not, this means your device doesn’t support FlipFont.
