Good sheep leather is squared 50 * 50, it washes well, it collects a little, however, peripherally because I take many pieces some have some small imperfections that are thinner at the edges, but for its price, it is very good, it does a very good job compared to synthetic absorbent microfiber cloths. I have been using them for years, I recommend them to you; if you don't try it, you won't understand the difference. It absorbs much more water than microfiber cloths and dries the car or the glass and does not leave moisture on top like the microfiber cloth does, it leaves shadows afterwards - if you maintain it properly, clean it after use and leave it with a little soapy water, it lasts many years due to its use, of course
