Shunga's Toko Aroma Formula is a flavored, water-based lubricant that is formulated not to have a bitter aftertaste. It succeeds admirably in this goal, and has no aftertaste at all, despite it being sugar-free. It does cause a slight numbing sensation on the tongue, but this vanishes quickly and is very, very minor. I have this in the Strawberries and Champagne flavor|Toko aroma formula - Strawberries & champagne, which has a very sweet and very intense strawberry taste and scent.

As a lubricant, the Toko Aroma Formula works quite well. It is fairly thin, and almost feels to me like a silicone lube--slick rather than slippery. I think it is better suited to flesh-on-flesh intercourse than toy play because of its slickness and thinness--it feels somewhat like natural lube. I personally prefer thicker and/or slipperier lubes for toy play.

It lasts well as a lubricant, needing little, if any, reapplications. I only found the need to reapply it for toy play which, as I previously mentioned, is not its best use. For partner play, one application lasted an entire session without drying out or being absorbed into the skin. It never became gloppy or sticky during use, and did not dry into crumbly bits.

Toko Aroma Formula does leave a slight sticky residue on the skin that is easily removed with a damp cloth or soap and water. It does not get gunky or sticky during play; just after play I noticed my skin was a tad sticky. Still, compared to most flavored lubes I have tried, Toko Aroma Formula is very clean-feeling in general; it really does not get any stickier (and actually is less sticky!) than many non-flavored lubes.

It comes in an attractive plastic 5.5 oz. bottle with a flip-top cap and is easy to dispense, as long as you remember it is a thinner lube. I am not generally a fan of the “Japanese erotic art” on the Shunga line of products, but the black and white drawing on this product is better than most of the line.
