Do not go for wiper blade rubber from open market. Stick to Honda 3S. Believe me they may be expensive but they last way long and do not put scratches on your windshield. Check with them if they sell only rubbers.
Many years ago, now I do not remember, I got just rubbers from Toyota 3S for 800 rupees for my Xli, they are still going fine. Actually the original rubbers I kept at a safe place were find, but I thought they were going away so changed when one of the replaced blade tore down. Now I can change myself, not a big deal, very easy to replace rubbers.
I some jobs or parts 3S are damn expensive, but in many areas they are not expensive, rather cheaper than open market.
