Pukeberg glass knife holders, Sweden 60's

Colorful knife holders in pukeberg glass sweden circa 60's. Lovely curved glass buttons on top and striated on the bottom. The whole is in its juice, perfectly presentable (pieces and case). It is worth noting a tiny ginning of use it seems, on one of the parts which does not harm in any way the aesthetics and the function of it (at the level cut of the glass button, at one end of the slot supporting the knife blade).
