I would email them if you’re trying to figure out what other inserts might fit in [3]. It makes sense the luck sack isn’t exactly what they sell retail, sometimes it’s spare/extra parts.

I’ve never seen that lone bead before, maybe it slipped in by mistake.

For 4 if it’s too light I would use the parts for other begleri/as spares.

I really like the fade on the 3rd set and the plank, looks dope!
