Lancet body (3) comprises elastic material into which the needle (1) tip (2) is embedded. Preferred features: In a development, the needle is movable within a hollow elastic body surrounding its tip region. The elastic body is penetrated when the needle is put to use, The tip is re-enclosed in the body, on withdrawal. The elastic material is a thermoplastic elastomer. It is stabled by a rigid material. In a set of such lancets, two are connected together by the elastic material. A lancet magazine is also claimed. This has independent chambers each with opening(s) for needle tip exit. The openings are closed by elastic material, which is penetrated by tip exit during use. each tip is sealed back into its chamber, on retraction.
