*** Note on shipping/delivery times ****
It has come to my attention that eBay is putting completely unrealistic expected delivery dates on order details that in many cases would be very optimistic in normal times for overseas airmail shipments, without delays due to the pandemic. eBay has no control over delivery times, and neither do I - it depends on the postal services, customs, etc. I normally ship next day on receipt of payment.
