If you're a fan of mascaras like Lancôme hypnose and benefit roller lash, get yourself some Collection lash surge! It's £3.99 in boots atm. It's very black, gives loads of volume and length! I did the maths, and for 4oz it works out at £2, whilst 4oz of roller lash is 10.50! I actually saw someone mention it on here ages ago, so glad I took a punt!
