I think with a few minor changes, the boxes would do fine sold separately. For example, if you put a little dent at the top of the handle, it can double as a yo-yo stand. In that way, it might compete with other yo-yo stands, and also double as storage for small items, and yo-yos. I’ll post a photo below of what that might look like. If the box were marketed as both, it could compete with storage containers, and also compete with any other table top yo-yo stand. It would be different, but those looking for an item that does both, and the fact that they lock together, might give it a better chance sold separately.
But, as it stands now, I think it is great multi-use, long term, low cost storage/display for people who own multiple YoyoFactory throws. I already own about 8 of them, just by keeping up with YoyoFactory products. I am not using them for display at this time, because I don’t really display yo-yos at home. Unless it is marketed differently, I think sold with the throw is best, and certainly a nice feature for buyers.
I am a fan of the packaging, and multi-purpose hard cases are always great. I tend to favor canisters like what Horizon is packaged in, or Superwide. So, the hard case, even more durable, was a step up, and a pleasant surprise for me.
