Tlapkaš¾ :neocat_phone: (nprofileā¦t4tm) As I was attending some conventions in Poland there is more and more Umamusume merch, so it will eventually come. I don't know fandom situation in Czechia so I cannot say for sure how it will be there.
Also in Poland those are mostly small artists selling their own works, pins, keychains etc. or general vendors selling figurines (it's 50/50 Japan or just straight Aliexpress).
If you're hunting for anything particular, let me know. I can always buy it for you and send it to you. I don't think it would be expensive to send stuff from Poland to Czechia.
