I have recently purchased a few items on TWE including the Rafa Crew in Iron color and Habanero color. I saw the description of these items on the website that the Nike and Bull logos on it are Heat transfer material. This is the case for the Iron Color. But when it comes to the Habanero one, it clearly is not the same material and instead is just normal print for the logos. I have purchased also the Rafa Crew in White for Wimbeldon from other source, it is also that heat transfer material. How come there is such a difference?
