Waterproof eyeliner pencils are a wonderful wonderful thing. I haven't owned a Stila pencil in about a decade, but after receiving Moray as a gift with purchase I see this changing. Moray is an olive-khaki with gold shimmer, but I see that Stila also offers the Smudge Stick Waterproof Eyeliner in several shades of blue. Since the performance of this eyeliner is comparable to other favorites I feel an urge to go and explore.
Stila Smudge Stick Waterproof Eyeliner is a thin automatic pencil that glides on the lid easily and stays put from morning to night. It requires a good cleanser for full removal (and a few seconds of soaking on the lid), so weather, tears, and light eye rubbing cannot make the color budge. Since there are shimmer particles I wouldn't use it on the waterline or for tightlining. The pencil is made in the USA and comes in the old familiar Stila cardboard packaging.
Stila Smudge Stick Waterproof Eyeliner in Moray (and ten other colors. $20 each) is available from Ulta, Sephora, and stilacosmetics.com.
