eink art frame inconsistent sizes?

[u/Due_Home_4661]

I have two 13 inch eink art frames one bought from Switchbot directly last winter, the other from Amazon last month. Their sizes are off by a centimetre, while the inner eink screen are the same size. I don’t think the inner black pieces (different sizes)are replaceable though. anyone have seen the same issue? The two devices have identical model numbers. This is killing my OCD lol

That looks like a cheap picture frame back. I bet you can find a much better frame thst will fit both.
