For sale Schwalbe Tire Booster

got this about a year or so ago when I was toying with going tubeless. but I never did and most probably never will. so here's me offering this to someone who'll have some use for it. I see it online for around 9,000 yen. wire me 5,000 yen and I'll include the shipping. I think it's a fair offer and am not ready to negotiate the price
