Well, it's a specialty item that can substitute for a very popular mainstream one in a number of popular use cases. And come close to substituting in a number of cases that might still lead to a bit of rapid adoption. More ideal as an incremental acquisition for many of those who already possess the mainstream merchandise. Not so much desirability for those that would have to choose one or the other. So that's a smaller subset of the niche. Then there are those who find the novel solution is superior for their particular needs, an even smaller subset, but more enthusiastic. Seems like the behavior would be to fly off the shelf until the subsets of the mainstream have been saturated, then plateau at the rate that the mainstream becomes amenable to replacement. At the smallest of scale, like with handcrafted items, it can occasionally be easy to do well financially as long as you can sell all you can make. This can happen when they're "flying off the shelf" so there can be relentless pressure to just make more, and the pressure can seem unending when there is a multi-year timeline for any scale-up activities. If the market matures at a less-giga-than-anticipated level, and you end up in the process of building more than you can sell on an ongoing basis, you have reversed the financial opportunity that was supposed to accrue by building more to begin with. One day when you wake up and can no longer sell all you can make for some reason, it's a whole different ball game.
