It's getting colder by the day in Japan, and during the winter months, the dryness sets in. If you have dry hands and find your fingers just too dry to handle the cards, try this:
1 part glycerin, 4 parts purified water.
This provides a sticky feeling to the fingers and hands, but does not rub off onto the cards. You'll find you can handle cards with a very light touch, and yet not impart any stickiness to the cards themselves. Palming coins also becomes much easier to do.
The solution has no odor and helps condition the skin as well. Glycerin is sold at any drug store in Japan, and so I'm assuming it is readily available in drug stores outside of Japan as well. I fill a small spray bottle with this and squirt a few sprays on my hands about 15 minutes before performing.
A friend turned me on to Chamberlain's Golden Touch Lotion. I later read that many magicians use this, including Dai Vernon back in the day. One thing that almost everyone mentions is the fragrance. It's not a particularly subtle smell, especially for men who aren't accustomed to cosmetic fragrances.
But more to the point for me is that it is not available in Japan. You can buy it by mail order, but shipping outweighs the actual price of the product. $110 by UPS or $49 by USPS for a three-pack of 8.75 fl. oz. bottles valued at only $23!
Destined to find a solution, I checked the ingredients and did some Googling to find out that you can make this for a very reasonable price.

My mixture can be made with just $5 or 6, and comes out to a little more than 16 fl. oz.
