I was looking for an online store where I could buy a 15mm diameter Crystal lens which had the Amethyst Gray design because I have been used to this for the past two years. I used to buy at another online store, but for this year, they no longer sell the lenses that I wanted. I only buy new lenses once a year since that is for how long you could use them safely. I also needed new lenses badly since I have an event on the 22nd of January.
