Well, I have no idea whether this shop is legit, but I just ordered some of these tips, sight unseen (I've never seen these tips in person much less actually use them). I'm just assuming I need the largest size b/c that's the way it tends to be for me...this shop purports to offer the kit w/ all sizes, or you can order 10 piece sets of any single size--color coded. It looks like they're based in Columbus, Ohio, and I submitted payment via PayPal...a bit pricey w/ shipping: not quite $25USD for 5 pairs of the orange Star tips. Hoping they work for me on my SM64 b/c fit has been a PITA for me
