Never mind Kate, I appreciate your having checked nonetheless, and you're right, it's not easy finding single pierced earrings which would suit a male and I figured that any singles on eBay would be half of an incomplete set, meaning they're second-hand, and therefore shouldn't be sold due to health regulations.

 

Still, it never occurred to me that there may be new single earrings available specifically for males, so thanks for the tip, and I'll see if eBay maybe has something after all. 🙂
