There's just no easy answer on this one. You're going to have the people that say "I'd be all in if ..." and then fill in the blank. The colorway is by far awesome, but then its also custom. GMK hasn't had the best reputation for manufacturing custom colors and there will be those that speak up about light bleed. 400 is a tough MOQ that Massdrop will have a difficult time pulling off (shipping and declared value will hurt the international buyers) and there's always Skidata+ and JTK Orange.
The problem for Massdrop is that their system isn't designed at all for handling buyer tracking and it makes it confusing for everyone as to how they count buys. GMK is an all or nothing kind of problem. Massdrop will break up the kit into smaller kits to "deflate" the list price but then that throws off how many "kits" they've actually "sold". Since Massdrop isn't going to be willing to buy all 400 kits and then sell them as "redropped" buys, this is nearly dead in the water.
The only way I see this working out for GMK and Carbon (tm) is if it is run as a group buy or sold to a store that will sell the kits through a storefront. The only other way to run it through Massdrop is for you to choose to break up the kit, increase the price, and sell at a MOQ of 150 for each kit.
Breaking the kit into multiple kits is the wrong approach. Its better the drop fails as a whole.
This drop will be only one kit which either will contain everything (expensive) or only needed stuff (low cost). Which approach i choose depends the approximate final pricing and moq (which i still dont have
).
As i said previously, if you want to sell gmk keyset then deliver something special. The german high quality is not enough for this price tag. I think the last succesful GMK drop was TA. Am i wrong? From my POV Carbon is worth to be special. Without any ignorance i asume it might be succesfull, despite me being most of the time pesimistic.
Anyway about light bleeding. Who could think TA would light bleed? I think this was the first gmk set with custom colors. Now we know about it. And ofcourse if it goes into GB this very important property will be bold and underlined for gmk. I think its clear you have to define the properties you want before ordering. Everything you didn't mentioned as property is a side effect (light bleed) or feature.
Please do not compare SKIDATA+ (in which i also participated because damn i love skidata) to Carbon. These two are very very very period different keysets in my opinion.
