Paper Savings Bond Options for Gift - US Domestic or Foreign

Hi all, My family has an antiquated tradition of gifting savings bonds to young relatives that I'd like to continue. I know that they're not a good hedge against inflation and that there are better investments out there, but I found savings bonds to be a good teaching tool, one that stuck with me through the years. I also realize that finding a paper bond is becoming harder, and I'm hoping to purchase an actual bond certificate and not a gift card. As the US Treasury Department no longer issues paper savings bonds, I'm exploring options from non-US countries. (I really do like the physical paper bond certificate, although it looks to be harder to find these days. Canada made a similar transition.) My base requirements in order (only the first one is absolutely required): \-Legally purchasable by US citizen with no foreign residencies or dual citizenship \-Minimum purchase amount $100 - $200 USD (open to going higher if needed, but I'd prefer smaller denominations) \-Paper bonds issued if possible, electronic is fine but I'm sentimental. \-Generally stable government in decent financial health, although my risk / reward tolerance is pretty high. Open to developing countries. Does anyone have any experience in this area? I recognize that this tradition is antiquated, but I think it's sweet and nostalgic. Thanks for taking a look.
