There is an industry issue when a manufacturer thinks charging $400 for a set of stickers are a good idea to buy and apply to a brand new game, cost less than $80 to make with material and printing, and will never need to own a set in game lifetime for either individual or operator.
Things like this used to included with production quality of past machines which were silkscreened cabinets, and were better quality. This is not restoration product that was redone from scratch and reproduced.
Do the math l, know what you are buying in this world, and be smart, owners.
This is a 300+% profit mark up.
Unless, you think $300 more is worth having a set of stickers purely for a "cool name".
