About Master Piece Thermo Mugs & Bags

Master Piece is best known as a Japanese bag brand with a strong focus on practical design, quality materials and considered construction. While the wider brand is closely associated with bags made in Japan, this collection is more focused and brings together compact everyday carry pieces, including co-branded thermo mugs and packable tote-style bags.

The Master Piece x Thermo Mug styles are suited to daily use, commuting and travel. Made from stainless steel with a 360ml capacity, they are designed to keep drinks hot or cold for longer through double-wall construction. The co-branded front logo gives the mug a cleaner design-led finish than a standard travel cup, making it useful for work, journeys and everyday routines.

The Storepack Ego Bags add a lightweight carrying option to the page. Made from SLOTEX®, they offer stretch, easy handling and a lower-impact material choice. The pull-cord packing system inside the mesh pocket means the bag can be stored quickly when not needed, making it useful as a spare bag for shopping, travel or carrying extra layers.

If you are choosing from this collection, start with the use. The thermo mug is the more practical choice for hot or cold drinks through the day, while the Storepack Ego Bag is better for flexible carry when you need extra space. Both product types suit people who want simple, functional accessories with a more refined finish than basic everyday items.
