Stickers are mailed in a first-class envelope from the US. The latest ones are more waterproof and UV-resistant than the first stickers inspired by /r/FarmersStealingTanks shortly after Ukrainian farmers started dragging away abandoned Russian tanks. I appreciate your support and suggestions but am not charging money or accepting donations. Instead, please donate what you would have paid for a sticker directly through Ukraine's official UNITED24 fundraising platform or another reputable charity. Ukraine's National Post and artists have done a great job producing stamps with these and other supportive messages and designs, including a tractor towing a hunk of Russian scrap. Order stamp sets on their official Postal Market. If you're here more for the US politics, support your chosen organization that is fighting back.
