I know this question must sound exceedingly silly and some may even think that this is another joke by me, but please be assured this is a most serious question.

I'm hoping someone can tell me where I might be able to find index cards with one side blank, and with lines on the other side. That's right, blank on one side, ruled on the other, with no other words or markings or what not. I know some cards out there are like "Stock taking cards" or whatever, but I don't want those because of the extraneous words and stuff.

I've been to almost every big bookshop out there (even the BIG bookshop at Clementi) and no one seems to carry these. If anyone has seen these, please, please, please let me know. Thanks a lot!

Get a blank business card and draw lines on the back with marker, they sell those blank business card in popular book store , in a transparent case like around 50 over or 80 blank cards i mean business cards size.. :D
