Sometimes, the least exciting purchase is the one thats most practical. Enter, cotton buds. Cottons buds are probably the least exciting things to buy - well, alongside pans which are the most boring things ever (can you tell I dont cook!) but you know what cotton buds are extremely underrated in the beauty world.
I've also found cotton buds a great way to create a smudgy/smokey eye look too. This is more of an on the go solution as obviously if you're at home, you can just use your normal eye brushes but if you're travelling or going from the office to a night out, then buds are a great solution.
A final way I use them is to clean up nail polish. I'm so messy when it comes to applying my nail polish so I always need to do a lil cleanup afterwards - I just apply nail polish remover to the bud and carefully clean around the nail. They're such a good solution and best of all, travel friendly and easy on the purse strings too!
