Merisi Sessanta
60% (Tsangan & MX-HHKB)
Sessanta is now the final design in my "Kustoms" series. Sessantacinque ran 5 years ago and this was the last chapter in the Kustom project. It has been a very fun series to work on and I've been lucky to have ran each of the group buys successfully with the help of friends in the community. A massive thank you to everyone who joined the GBs. I can't put into words how grateful I am for the support! Thank you, thank you!
I ran a private GB for Sessanta before the public run. The photos and videos in this thread are from the participants in that project. The public GB offered Black and Silver color options. 
"Kustom"
Sessanta features similar design aesthetics to (for example) Sessantacinque and Ottantaquattro which were introduced in 2020 and 2021. The "Korean Kustom" side handles, substantial bottom weight, traditional top-mounted switch plate, and a clean USB cutout. The top case side proportions are slightly exaggerated to make room for the distinct 45 degree chamfers on the outside as well as the "user facing" inside chamfers. All of these design elements are also present in my previous "Kustom" designs.

Group Buy (Completed)

After the initial "Kustom" orders, the remaining MOQ spots were sold via FCFS on June 6th.
The Group Buy is now complete, and all orders have been fulfilled. Thank you to everyone who joined!
