Mum's Favourite Serum

For the sibling everyone agrees was always treated a little better.

Keep For Family Emergencies · 20mL

A favourite sibling gift for a sibling who claims favourite-child status. Mum’s Favourite Serum gives the joke a serious laboratory-style label on a 20mL glass display vial.

About this gift

Favourite sibling gift

An imaginary family tribunal has received another entirely impartial claim to favourite-child status. The supporting evidence includes a generous interpretation of childhood photographs and an unusually confident witness statement. No other siblings were consulted before the case was filed.

With Mum's Favourite Serum, the label carries both the introduction and the punchline. “Keep For Family Emergencies” sounds appropriately departmental; “Keep out of reach of in-laws.” rather undermines the professional impression. The result is a compact fictional exhibit that can start a conversation without needing you to explain the entire imaginary investigation.

Who it’s for

This is for a sibling who enjoys the ongoing contest and can give as good as they get. A birthday is the ideal moment to recognise their remarkable confidence without conceding a single point in the family argument.

In the UNLICENSED LABS collection, Mum's Favourite Serum belongs to the Family range. That context makes it easy to pair the recipient’s particular sense of humour with a design that feels intentionally chosen, whether this is their first imaginary specimen or another addition to a growing shelf of curiosities.

What you get

  • A 20mL glass vial carrying the Mum's Favourite Serum design.
  • A printed 50 x 30mm label with the Keep For Family Emergencies subtitle.
  • Lab green coloured display liquid, intended for decorative display only and not for use.
  • A small birthday keepsake for a sibling who claims favourite-child status.
  • The fixed Mum's Favourite Serum wording, supplied as a standard, non-personalised design.

Why it makes a great gift

Present it as evidence that their lobbying campaign has finally reached laboratory level. Expect a rebuttal, an appeal or a smug photograph in the family chat almost immediately after unwrapping.

How to take it
  1. Announce the imaginary MumFavourite Serum file.
  2. Present to a sibling with a straight face.
  3. Accept all birthday remarks as fictional testimony.

Guidance only — not medical advice. Always follow the instructions on your own label.
