Thank-you chocolate works best when it's small enough not to feel like overcompensating but real enough not to feel automatic. The boxes below strike that balance.
Two-piece sealed box with a hand-written note. Slip it into an envelope with a card. Most under-used chocolate gift on this list — small enough to feel sincere, real enough to be remembered.
Six-piece assorted box with a printed flavour card. Hand-deliver or send courier delivery. Works for hosts, hairdressers, mentors, and anyone you've leant on more than once.
Twelve-piece 'Twelve Houses' box with a handwritten note in the lid. Goes well with a single-origin bar as a follow-up.
A two-piece sealed box for a small thank-you; a six-piece box for a host or mentor; a twelve-piece box for a substantial favour. All include a free hand-written note.
Yes — particularly a six-piece welcome box with subtle company branding on the inside of the lid. Comes across as considered rather than transactional.
