Yes. There are two tool free links and a number of links with standard bracelet pins. Removing two will make it medium sized, though the engraving will still say large. They’re not marked or split or whatnot so theres no easy way to know which way they come out unfortunately, so I’d recommend bringing it to a jeweler unless you’re confident and have done it before.
Also I know this works because one of the pins in mine was installed backwards and would constantly work itself out while I was wearing it so I flipped it correct and gently hammered it into place, and it’s been secure ever since. Have worn it every day this month so far.
