"First, know that you must take off the white cap and clear tip to get the stopper out. Also, be sure to replace the stopper after use to prevent drying or leaking.
Second, many of the colors do look more vibrant in the photo. Red is definately more salmon colored. We found that the best coverage when dry was from the blues, dark green, and purple.
Third, you need to help younger ones to make sure they don't squeeze too hard and overfill the small areas. Our 4 year old did get lots of air bubbles since she did lots of squeezing and stopping. They were easy to pop with a toothpick.
Knowing all that, I would highly recommend this product. You don't need to use brushes and the colors are easy to wash off fabric and skin. The glitter sparkles in the sunlight and adds a more festive look."
