Keep names readable
Short names, initials and simple fonts print cleaner than very thin or highly decorative lettering. Readability matters most on small keychains.
Choose colours with contrast
Light-on-dark or dark-on-light combinations help names and logos stand out. Bright colours are good for friend groups and return gifts.
Plan packs by occasion
Pairs suit couples or best friends, packs of 4 suit small groups, and packs of 6 or more work well for events and teams.
