Maybelline 'The Falsies Volume Express' is not only a good, affordable mascara, it's easily better than some of the really well known, really expensive ones.
Sorry about the large picture of the wand but it's so you can see the formula is wet, which sounds really silly, but in the world of mascaras is becoming increasingly rare - in my experience. The brush is curved, but not too curved or too rigid - it lets you build and layer to get the effect you desire.
Available at the usual stockists - for around £5.00. Bargain.
