What the ad shows
A packaging presentation board for Kinokuniya's Offset Boxset shows three tiered book boxes, named One Kilo, Three Kilos and Four Kilos of CO2eq, each a different coloured box photographed on its own or being carried. Side panels list the exact titles inside each box with each one's reading time, matched to offset the CO2 generated by that many hours spent on social media, closing on a claim that the books are FSC certified and printed by carbon-neutral companies.

Kinokuniya: book boxsets sized by kilos of CO2 offset
Kinokuniya. Agency: Saatchi&Saatchi. The ad itself is shown at adsoftheworld.com.
The pattern
This still is filed under Reason-why.
Define
A specific reason the offer is priced, timed, or structured this way. Not a mood. A reason.
Mechanism
Justification. A concrete cause makes a claim feel earned. Because we overbought. Because the season ends Sunday.
Verdict
The price or the ask looks irregular
Why it works
The box sizes are justified by a specific, inspectable cause rather than an arbitrary price tier, since each kilo figure is tied to a stated number of social media hours that produced it. Listing every included title with its own reading time itemizes the claim on the box itself instead of asserting it, and naming the tiers after the benefit unit rather than the contents turns a bigger box into a bigger good deed, which quietly upsells basket size.
The big idea
Each boxset is named and sold by the kilos of social-media CO2 it offsets, with the books' reading time matched to the screen time that produced those emissions.
The offer
Kinokuniya's Offset Boxset book bundles named One, Three and Four Kilos of CO2eq, each with titles matched to that many hours of social-media use; no price printed.
The proof
Per-box line stating the social-media hours generating that CO2eq (14 hours for one kilo, 56 for four); side panel listing each title's reading time; FSC certification and carbon-neutral printing claim.
Steal this when
A product can be sized by a measurable benefit the buyer already worries about: name the SKU tiers after that benefit unit and give an honest, inspectable reason for each size.
The emotion
Written to Guilt. It makes the Say move.
Each box names the social media hours behind its CO2, 14 hours for one kilo, and offers a specific repair: books whose reading time matches those hours.
