+      'h-5 py-1 rounded-3xl flex-col justify-center items-center gap-2 inline-flex',
       isActive
-        ? 'bg-state-accent-solid'
+        ? 'px-2 bg-state-accent-solid'
         : !isDisabled
-          ? 'border border-text-quaternary'
-          : 'border border-divider-deep',
+          ? 'w-5 border border-text-quaternary'
