The cheapest Laneige Water Sleeping Mask sample I've ever found compare with other websites. If you buy 5 of this little baby, you get more than the full size (70ml) for cheaper price :))
The sample size bottles are value for money compared to its bigger counterpart. On top of that, I find it more hygienic to use as each bottle has less time exposed to air. It's convenient for travel and I always bring one with me when I go on flights to cleanse and moisturise my face on long flights.
