good. Again the hammer caster is good. I used a 75φ caster so far, but I want a large size at the same time, I found 85φ here and bought it. Because it is a rubber wheel, the sound is quieter than the nylon wheel, but because the wheel is nylon, the whole is feeling lighter than rubber ones. I am worried about how strong it is, but I have to try using it for several years. . . It's like that. It seems like inventory stock, delivery takes about six business days. When purchasing, I think that it is better to order with more margin in days.
