Small or Folding Bluetooth Keyboards for iPhone SE2

Hi everyone. I just pre-ordered the new iPhone SE, (or whatever they're calling it), and am now in the market for accessories. I'm upgrading from the original SE with which I've been using a Bluetooth keyboard case I found on Amazon. Unfortunately there don't seem to be any similar products out there for the new SE or iPhone 8. I've gotten somewhat better at using the onscreen keyboard, but I'd still like the option of an external keyboard for more involved typing tasks. I'm looking for something relatively small, easy to pack away in a purse or messenger bag. Compatibility with multiple devices is nice, but not necessary. Under $50 preferred, though if you've found a more expensive option to be more durable or long-lasting I'd consider it. Thanks in advance for your help and suggesttions.
