Protected 18650 button top cells

I been looking around for a case to fit these 18650s. I just bought a couple batteries from a website and it fit the flat tops but it won’t fit these protected ones. Anyone have any suggestions? I was thinking the 21700 case will fit but will it rattle a lot?

21700 battery case might cause the 18650 batteries to rattle…

Why not check for 18650 cases that do fit protected 18650

For instance, I’ve had some 2x 18650 plastic battery case that can only fit flat-top 18650 batteries, but some that fit protected 18650 batteries.

Yeah, I have been looking but it seems like most reviews say it doesn’t fit protected 18650. If anyone has a site that has cases that fit them please let me know! Thanks everyone.
