The product is excellent, despite its maturity date in 10 years. A previous model bought in 2014 had its coating melt out and had to be discarded.
However, paying 50% of the item's cost in delivery, duties and taxes is unacceptable nowadays. Wake up, sell through Amazon, and you'll discover an untapped market that thousand other sellers discovered 20 years ago. This would make your product more available globally and more reasonably priced in its logistic expenses.
