So about あちゃ's onahole, good news and bad news.

The bad news is, if you live in the US, de minimis is ending tonight. That means if you ordered the onahole from a Japan based retailer like OtonaJP or Kanojotoys and it hasn't already shipped, your order is likely to not only get hit with duties, but also possibly searched/delayed at customs. That's assuming your order isn't outright cancelled.

The good news is that Toydemon has listed the onahole in their poll section, where people can vote for it for them to stock it. Since Toydemon is a US based retailer, you can avoid import shenanigans if they stock it.
