Take a small amount on a polishing cloth and work it into the leather, a thin layer is enough. Let it dry for 5-10 minutes and then brush it up with a brush. If the leather is dry repeat the procedure.
Since the lotion is completely colourless and doesn't smudge it can be used on all types of leather products to moisturise, nourish and protect, and can really bring back and prolong life to hard worn leather. Use it for briefcases, wallets, hand bags and so on.
How often you should use Saphir's leather lotion depends on what the product is exposed to, but at least once a year.
