The Spring Stacking Mug Set is our inaugural limited-edition seasonal collection celebrating nature's cycle. Made from ultralight Japanese titanium, this two-mug set pairs the H300 and H450 in an exclusive anodised spring colour-way that reflects the season's spirit of growth and interconnection. Each mug features double-walled titanium construction for superior insulation and durability. The nesting design allows both mugs to stack compactly for storage and portability. Each purchase of this mug set will include a stamped insert with the your own individual number out of the global 1200 mug sets made. 

Note: Double-walled titanium should not be used directly over open flame or heat sources.
