Airam Glass Vacuum Flask, 0.45l

A silvered glass Dewar flask from northern Scandinavia. First produced in 1934 by the Airam group, these are a legacy product, something that helped build the foundations of a company that has since shifted focus to other more lucrative fields but has continued in production none-the-less, and to which they are proud to be associated. These are proper glass vacuum thermos flasks made for the rigours of the arctic winter which promise, even in those freezing climes, to keep boiling liquids above 50°C for at least 24 hours. Being glass, these are breakable (don't drop them), but careful handling is more than adequately rewarded by a hot cup of tea.
