If you know some one in the US there’s these ones currently available, https://www.amazon.com/Fujifilm-Instax-Instant-Stickers-Cleaning/dp/B08YBY923J/ref=mp_s_a_1_3?crid=34C2XOE9ZLV72&dchild=1&keywords=instax%2Bsq6&qid=1635266000&qsid=133-2528296-1537845&sprefix=instax%2Bsq%2Caps%2C173&sr=8-3&sres=B08YBY923J%2CB07XTPCNZH%2CB07CV6XRBD%2CB07CW3LYZY%2CB07VFH3W4G%2CB08G6B6V4X%2CB07QRG8SLM%2CB098T9SF26%2CB08KMNN7PQ%2CB00M1XIPKG%2CB07DYQ6Q65%2CB08NTWY88N%2CB016CRZGGC%2CB07DWSZVZQ&srpt=CAMERA_FILM&th=1&psc=1 and they’re shipped by Amazon. The issue is how do you get it to France (or to Ireland for me) without paying a an absolute fortune and then also customs/import taxes?
There is a service by our national postal service to have stuff shipped to an address in the US but you get screwed on import taxes. I ordered some AirPods last year that were on sale in the States, ended up paying nearly the same price as I would have getting them from Amazon UK (but still slightly less than I would have paid here in Ireland if I bought them locally).
