This kitting is normal for SA sets. Some SA sets run full base kits but very frequently run them a la carte like SA Espresso did. Pretty much all Signature Plastics SA sets on Drop except SA Godspeed ran kitting like Espresso for example. Also, Kono doesn't dictate kitting on SA sets and kitting is usually agreed upon by the designer and the vendor.

By all means, we should be shitting on Kono for the prices they charge. But the kitting here was standard was standard and solid. OP just made a mistake in assuming a novelties set was meant to kit a 65% keyboard's modifiers. If he was too lazy to look up 65 modifiers sizes himself, he probably could have asked the designer in the reddit group buy thread and the designer would have told him exactly what he needed.
