Midori is one of those not-quite bit players who made a few distinctive but always obscure MPs. I think of them in much the same vein as Sun-Star.
Aside from the GROOVY… what else? I think only unfortunately named ‘SLIMMY’ flat design, and a couple of ‘CL’ branded compact pens and pencils from the mid 2010s. Nowadays, they make notebooks and mini stationery sets. And some nice aluminum rulers. 
PS. Midori is also the maker of Traveler’s Company leather-bound notebooks and brass pens.
