>>9682099for the 80-90cm dolls they are REALLY not a big deal to maintain, infact its low maintenance compared to the bigger dolls. As ive said ive had mine for over a year and its still practically factory new. its just all about how you store it and how often you "use" it.
I keep mine in this here flight case however i will say that the main downside to this is that overtime your dolls ass may get a bit flat from laying in their too long... which is quite a shame. but aside from that she stays fresh and new. all you really need to do is oil and powder her after giving her a soap and water spray bottle bath. takes all of 15 mins and you only need to do it either once every other month or after each "use". and even after using her you only really need the spray bottle bath and powdering. its actually comfy believe it or not.
The real pain of maintenance comes from the adult sized 140+ sized dolls as they are heavy and take more effort.
