Het Muizenhuis - Sam & Julia

About us

The Mouse Mansion is an international children's brand, built around the handcrafted miniature world of Karina Schaapman. The books about the mice Sam & Julia are published in 27 languages and can be found in more than 40 countries. From this storytelling universe we develop a wide range of products: picture books, plush, toys, craft and DIY kits, dollhouse accessories and gift items that invite children to play, build and imagine for themselves.

A dedicated community has grown up around the brand: fans share their own mouse mansions and creations with us on social media every day. This active following builds recognition and brings customers who actively seek out Sam & Julia products — a brand people keep following for years rather than buying just once.

The timeless, handcrafted style and recognisable characters make the brand a strong addition to toy shops, bookshops, museum stores and concept stores. With our own museum in the heart of Amsterdam and a growing international fan base, we offer retailers a brand with story and quality.
