Singapore may be many things to many people, but there is one tag it seems unable to shake off it&rsquos just too clean. So it only seems apt that on my nth trip to the Lion City, I got back this C-Stub pocket ashtray as my top buy. Available at 7-Eleven stores all over Singapore, this nifty pouch, which has a foil lining on the inside, takes the drag out of responsible lighting up (&lsquoDon&rsquot be a tosser,&rsquo admonishes the packaging, while promising a shelf life of six to nine months). So no hunting for the smoking zone, no fretting about how to keep the ash off the grass. There&rsquos only one catch, though. It looks a little too clean to use. And it&rsquos a bit pointless if, like me, you live in a filthy city. So I think I&rsquoll just have to go back to use it.
