I came across them on tiktok but if I remember right, they were on dragons den? They have a cool concept. You pick your base pair and then from then on, you can just order toppers to change the look of glasses whenever you want! I have my base and then I believe 3 toppers and 1 sunglasses topper
I didn’t find them to be expensive but they’re not as cheap as zenni. Depends if you are looking for inexpensive glasses or just sites in general where you can buy online. It’s just a general site that I thought I’d share
