She comes home in her own bed. The matchbox is printed as a Mouse Race safety match packet, the sleeve pulls out to make a bunk, and inside there is a mattress, a cream pillow printed with coral dots and a sage green knitted blanket for her to lie on. The whole thing shuts again and goes in a coat pocket, which is why these get taken to grandparents' houses and on car journeys.

Her pajamas are a fine coral pink check, a short sleeved top with a cream lace bow at the neck and matching bloomer shorts, and her ears are pale pink. She is a Little sister in Maileg's family sizing, 4.33 in tall. There is a magnet sewn into each hand, so she can hold a tiny metal cup, carry a lantern, or hold hands with another Maileg mouse and stay held. Cotton and cardboard, filled with recycled polyester and PE pellets. Other items pictured are sold separately.

Maileg lists her as Little sister mouse in matchbox, item number 17-5109-00, made in China. Maileg's play age for her is 3 and over. She is not a toy for a child under 3.

Her brother sleeps in the matching box in sage mint: Little Brother Mouse in Matchbox. For a pair already boxed together, see the Royal Twin Mice. Maileg sizes its mice by family role rather than by measurement, and says each one is handmade so heights vary a little, which makes the size name the thing that decides the fit.
