Each of the five has its own page, because a launch rarely needs all of them at once and you should be able to read only the part that applies to you.
Brand identity
The full identity system: wordmark, palette, type, and a style guide that lets someone else apply it without asking you first. This is the one productized service — it has fixed packages rather than a quote.
Packaging and print
Boxes, labels, inserts, catalogues. Dielines built to a printer’s spec, not a mockup that falls apart at prepress.
Digital templates
Email and newsletter layouts, social template sets — the things you have to produce every week, built so producing them stops being a design job.
Product photography
Not art-directed out to someone else: the person lighting the product is the person who designed its packaging. On-white for listings, in-context for everything else, lit so the material reads the way it does in your hand.
Illustration
Technical and instructional illustration, including assembly guides and how-to sequences — the drawings that decide whether a product gets used correctly.
Why one designer instead of five
A launch bought as five separate pieces tends to look like five separate pieces. The box says one thing, the listing photos say another, and the instruction sheet was clearly done last. Nobody plans that — it is what happens when each piece is commissioned from whoever was free.
Working through one person means the palette in the style guide is the palette on the box, the photography was lit for the ground the identity actually uses, and the illustrations share a line weight with the logo. That is the practical argument, and it is the only one being made here.
