My nickname is flexagoon, written exactly like that. You cannot change any letters or capitalize them in a different way. First letter should not be capitalized, even if in the beginning of the sentence.
This is not a hard requirement, however, my name should preferrably be written in the Inter font. More specifically, you should use the Extra Bold Italic variant.
You can download my logo in three variants here. All three variants are in the SVG format.
The white and black variants can be of course recolored to a different color with any vector graphics editing program.
