I was able to buy those plastic being used for shrink wraps (sa U.S. nga lang). I just need to use a hairdryer to seal it. Looks brand new again.
I used to this as well but not with a hairdryer.. I use a "sealer" that's being sold in hardware shops.. bought it for P1200+ dati.. naubusan nga lang ako ng plastic so I stopped.. still have the "sealer" though..
