The beautiful grinder Elektra Nino Version 2017 needs the Glass Adapter Macap 2 now. Former models of this Ninp Grinder were equipped with the Mahlkoenig K30 Hopper. If you would like to go for a Nino Glass Hopper, please check your version or provide a picture to be sure which one will fit.
As for the size of the Glass, all options (300/600/1300) will work fine although this is a huge grinder. This picture shows the 300g Crystal PUR model plus high gloss metal parts and it looks really nice. The glossy finish is the perfect match for the chromed and polished Elektra NINO.
