I don't know how much of a shine beeswax will impart. My experience is that it yields more of a satin or semi-gloss finish. Also, I expect a briar with beeswax would be be fairly sticky to the touch unless it were polished off with a cloth or whatever. Carnauba wax, usually the preferred wax for briars, is very hard, which is great for a protective finish, but it needs to be applied with a buffing wheel and polished off with same. FWIW, I think dave from Walker Briar Works still sells his carnauba wax/polisher, but I've no idea what the cost would be to ship to Iran. Cool stuff tho, it's carnauba wax combined with some sort solvent into a soft paste. What you do is wipe on to your pipe, briar and/or stem, and the solvent evaporates off, leaving a fairly hard carnauba wax that can be finished with a polish from a soft cloth...all by hand.
If you go with the beeswax then you could try applying it to the briar after a smoke when the wood is still warm or try melting some beeswax in a double boiler and adding a bit of oil, like olive oil, and the resulting blend should be much softer at normal room temeratures. I even read somewhere of recycling empty chapstick tubes by filling them with the beeswax-n-oil mixture and allowing it to cool, then just work the stuff onto your pipe when its warm. I'm pretty sure the latter was applied to a meerschaum pipe, but the choice is yours!
The Paragon and Halcyon II products also seem to work well, if you choose to go that route. Good luck friend.
