Hair ties arranged in colour, not in packs.
I've never thought to blog about these because they're everyday, boring items. The boring products are often the most useful though. Primark hair ties come in packs of 30, including both thick and thin variants, and are priced at just £1. As you can see, I've bought quite a few packs! The best thing about these hair ties (apart from the price) is the fact that they are elasticated all the way around and don't have those annoying metal bands on them.
I picked up the hair elastics the other week, after looking for some for months! I use these when I plait my hair.
