Make sure the person you're messaging is trusted and do not use PayPal Friends & Family for your purchase, this is a common tactic for scammers. Keep safe!
I was going to offer one up I had bought around 15yrs ago...pre-Amazon-juggernaut times.
But I just looked at the link above and also saw this one too:
Amazon product ASIN B09PTXYQDV
These are very similar to what I've used and do the trick very cheaply and effectively.
Hope this is helpful and not deterring from your search.
