This is a Chinese product purchased on AliExpress. I've used it a few times. There were small scratches from the beginning. I'm satisfied with the purchase, but I haven't used them much, so how about it? I think they cost around 1000 yen for two. ◎ Set of 2. ◎ Various colors Transparent green Muted, non-transparent light blue They are hand-sized, but I'm preparing to measure them in detail. I will ship them in a Takkyubin Compact dedicated box! This is a bargain price for a set of 2. The price is firm due to the cost of the box and shipping.
