Most RSO is sold direct through Elvin iirc. According to his site, there are 37 unknown udon bowls:

A decent portion of his sales are pre-sales, then there was a drop available directly on his site a month or two back.
Elvin is pretty strict on quality control but I’m sure he also works with a very high quality machine shop. Let’s say he ordered 80 halves and ended up with three b-grades. Idk how many retailers are getting the udon bowl, stateside or otherwise.
So, 37 available, let’s say 7 sold to pre-sales, then perhaps 20 were available directly during the drop, that leaves 10 available to retailers. Say 3 retailers were interested, each were probably offered the ability to buy up to three, and once those had been allocated any remaining were maybe offered to retailers interested in more stock.
But say 25 were sold direct, that would leave only 5 available for retailers.
Maybe YoYoExpert only had the extra capital to order two units, or maybe two was the max available.
Why not order more halves then? Well for one I imagine titanium throws are expensive to produce, 80 halves may have been all that could be budgeted for. Also you do not want to have excess stock sitting around especially if you mainly sell direct to customer; you want to order the max amount that will sell out quickly. Plus it’s a special edition of a yoyo that has already had other releases over the last couple of years.
Regardless, the best way to purchase an RSO I’ve found is directly from Elvin and that outside of the bigger drops the ones that YoYoExpert receives are more of a convenience if you didn’t want to order internationally or last chance to grab one if o you missed the main drop.
Since YYE only has two and interest in this yoyo is high and to avoid a whole bunch of people desperately trying to check out, getting their hopes up with it in their cart only to get an “out of stock” page (like we saw with the Mowl Surveillance release), a drawing for a chance to buy one seems like the fairest way to sell them with the least amount of disappointed people, since everyone who’s interested will have an equal chance at winning.
