Andiamo piggyback-strap?
So now that Andiamo and whoever bought them are out of business, I've been searching in vain to find the replacement "straps" you can use to connect the smaller and larger pieces of luggage together. I have both 25" Valoroso and Tuxedo, as well as smaller wheeled carry-ons from the same lines, so I'm looking for a couple of straps (don't know how they went missing). They have buckles on both ends but are otherwise just straps.
Alternatively, I could buy one of the third-party straps, but if I can find something that uses the built-in buckles on the Andiamo luggage I have, that'd be great.
Any leads/ideas?
