Almost completely hairless, the Metmin are famous for their distinctive high craniums and for the prodigious amounts of natural oil that they excrete. Approximating a pinprick in size, their pores are ordered into rows that zig-zag in an orderly fashion across their skin, which is bright pink in colouration. Additionally they have large openings on the far sides of their legs and arms which starting from the neck traipse in a series of biological ‘craters’ all the way down to their ankles. It is here where the majority of their secretions are produced, and poking inside one of the larger holes will reveal that a thick film collects there to guard the opening from infection - which nevertheless has proven a significant obstacle to their good health. Generally odourless and one of the greatest aids in maintaining the elasticity of their skin, most of their kind are still quite embarrassed of the discharge that they produce and will often take pains to ensure that they don’t brush up against other people. They prefer having specialised patches sewn onto the legs of their pants or the hem of their favourite shawl, and use these to very quickly wipe off the grease that pools at their fingertips. In this way they can avoid needlessly dirtying the pieces of public infrastructure that they interact with, although their careful consideration is often made redundant by other lazier, equally slimy species.
In the privacy of their own homes they take no care to wipe away any oils, and actually find that once congealed they are very pleasant to the touch. Hardening but never truly losing their stickiness, a Metmin’s excretions can be easily identified by their almost total transparency and by the flakes of dead skin that they have floating inside of them. In a domestic setting this stuff starts to accrue rapidly in places where they rest, and can come in only a short time to drown handhold objects. Where they have lived long term it builds up on the walls and floors and seals everything beneath a thin, highly glossy film. Interestingly this substance has proven greatly effective at maintaining whatever it envelops in stasis, and it is for this reason that the normally squeamish Metmin are common as assistants to forensic specialists. The quirk is also responsible for their custom of buying perishable goods for one another, and then sealing them inside of a mixture of their oils - from then on having a constant reminder of the happiness that they felt on that special day.
Despite finding the sensation of fabric brushing up against their skin abhorrent, most individuals choose to wear a few layers of a very stiff material when they leave the house. These are thick strips of fabric worn commonly as single piece ponchos, and their rigidity is to stave off the time it takes before they become entirely soaked through with grease. Adorned sparsely with white ochre on the outside, these are otherwise utilitarian grey robes that the Metmin find to be complementary to the garish pigment of their skin. Beedy and jet black, their eyes are obscured beneath heavy folds that give them a half-lidded appearance. This also lends the impression that they are perpetually annoyed, but is actually just an expression borne from out of deposits of fat which bulge in place of eyebrows. Very materialistic and possessive culturally, they start to covet random objects and get a strong urge to preserve them, sometimes coming off as annoying to other people who don’t want to give over their things. Although this might imply they would make talented hagglers, Metmin can be overzealous in their spending if they perceive an item to be of enough value, and their awkwardness sometimes prevents them from making offers to somebody's face. Strictly monogamous as a rule, they become far too attached to one another to even consider the possibility of parting ways, and for that reason marry for life. An elderly Metmin whose partner has died will struggle to find somebody new because the others of their age are mostly already engaged, and can spend a lot of time with the things that they gathered up together in their youth. Trying earnestly to tell if the flakes of shed skin suspended along with the object are those of their beloveds.
