On my recent trip to Poland I bought three jumbo pencils in a Sephora shop there - it was a hot Polish summer and I needed something waterproof - one a very pretty shampagne pink beige from Make Up For Ever and two cheaper ones from Sephora's own brand: 15 Purple (a dark violet with reddish specks) and 07 Brown (warm deep brown with coppery specks).
The Sephora pencils turned out to be winners - the idea of them is very similar to MUFE Aqua Shadow pencil except that one has to sharpen them instead of just turning the pencil's end (which seem not to be working with my MUFE pencil anyway - what a waste of money!). They sharpen without wasting too much product.
I mainly use them for a quick makeup fix: I smear the colour into my upper lashes and waterline and also a little bit above the eyelashes on the lid. A bit of finger smearing, some mascara and I am done.
I am a contact lenses wearer and these pencils do not get onto the lense's surface and do not make your vision cloudy. They set quickly and indeed waterproof but get off without any problem with my Garnier oil & water makeup remover (Bioderma Crealine was useless, you need a two-phase eye makeup remover for these).
I am looking forward to getting more colours of these (maybe a navy and a white one?) during a visit in another Sephora hosting country.
