Not your usual lubricant, Wet warming gives you a warming sensation when they go at it. It is as safe as any other brand-name lubricant but quite a surprise for your partner. Even it's hologram printed bottle shows that this is not some cheap backyard-hokus-pokus. Isn't a 105g-Bottle exactly the right size to try it out? Fits in your hand, into every luggage but is big enough to do a lot of comparison together ;)
