i bought an apple pencil in the united states but i can't replace it with a free 2 year warranty because i'm in another country.

Since you made your original purchase via Amazon,

you will have to work with them to resolve the matter.

If you had purchased from Apple, the answer would be

no, Apple will not ship you a new pencil internationally.

Apple doesn’t have >free< two year warranties. Who is the warranty through? Did you purchase from Amazon and they did they just do fulfillment (shipping etc) or was Amazon the dealer/Seller and shipper (fulfillment)?

What was the exact date of purchase?

Is the 2 year warranty you are referring to AppleCare+ that you purchased with your iPad and covers your pencil? If so, then no…Apple will not ship a replacement to you outside of the country of purchase. The terms and conditions for AppleCare+ does state that hardware claims may not be covered outside of the country of purchase. If it was a different warranty provided Amazon you would need to contact them to see what your options are. Otherwise you may have to go through the tedious process of shipping your current Pencil back to someone in the US and having them ship you the replacement that Apple sends if that is possible. Otherwise if waiting isn’t an option you may have to purchase another pencil

Products purchased within EU Member States have at least a two year warranty.

He says he bought it in US. I doubt his EU status covers it.
