These are my latest purchase
I got them from EBay, £6.25 for 600, Link! from a seller called Pinkcandy1005 They come in clear, natural opaque and white. I choose white as it makes bright colours look better. The nails are great quality and arrived within 2 days. As you can't seem to be able to get stilletto shaped nails in Boots or Superdrug, these are a affordable option.
I also attempted to re-create a nail art look I'd seen on Instagram
They are too long though. Typing at work was a trial today so I shall experiment with trimming them down next time.
