Hello,
Could anybody suggest where I could find a slim and small lighter that I could put it in my wallet? I am trying to find it on the net, but cannot find anything properly slim and small. Cheers

What do you mean by "a lighter"? If you mean a butane-fuelled disposable lighter, I doubt you could fit one in your wallet. But you could probably glue some lighter flints to an old key and store that in the coin pouch. I carry a credit-card sized plastic Fresnel lens (a flat magnifying glass) along with my credit cards and driver's license.

I haven't tried it personally, but I believe some people here have stored a "Military Match" successfully in their wallets. That's a very compact magnesium rod with a flint striker built into the side (I think).

I put small BIC lighter into my wallet.Surprisingly, it did not take a lot of spacel! Of course, it would be even more convenent if I could find something even smaller, but I do not think I will find anything smaller.

You can buy novelty cigarete shaped lighters in some shops in UK. I dont own one so I couldn't say how they perform
