Only part of the order shipped
I paid on April 10. Kazumi’s June 29 shipment notice listed the brewer and beaker—but not the Toki.

Nothing from my $423.47 order shipped for 80 days. By day 114, the $199.99 Toki still had not shipped. The lower flask cracked during use four. Kazumi’s current Terms say it keeps 55% when a customer cancels after the first day—even if the order is delayed.

These are individual posts, not facts I independently verified. I include them because they describe the same delay and cancellation themes I encountered. See the dated review summary.
What I recommend instead
I receive no commission from these links. The Yama recommendation is based on my own use; the Hario is included because it also performed well in independent testing.

I switched to this model and love it. Serious Eats also named it its top siphon pick after testing four models, highlighting its even heating, stable flat base, wide opening, and sturdy handle.

I have not personally used this one. Serious Eats named it another winner, praising its build quality and consistently flavorful coffee while noting that its separate alcohol lamp or butane burner makes it trickier than a stovetop model.
My opinion, plainly
The wait was excessive to me. A lower flask cracking during the fourth use was unacceptable. And I consider a policy that retains 55% after a delayed order far too restrictive.
The “custom-made” justification
Kazumi’s current Terms use custom production to justify keeping 55%. But its listings show fixed products and limited standard choices, while a saved email refers to production batches and the Toki page describes incoming preorder units.
I cannot verify how the products are manufactured. In my opinion, Kazumi has not publicly explained what is customized for each buyer or what customer-specific work supports the fee.
