Purchased a year ago and used about 3 times indoors, applying silicone spray. I think it's worn down a little, but the condition is good because it hasn't been used much. Silicone spray is also included. Here's a description of the product: The most recommended standard set! With 12 pieces, you'll have enough space for practicing ground tricks. It supports various tricks, and you can seriously master the feeling of gliding and edge control. This is the best choice set for off-season training and home practice! * The board is 150cm. * A set that's 8400 yen cheaper than buying the items separately. Shibakatsu's single piece size is 20 x 40 cm. You can freely customize the layout, and it can be divided into smaller pieces for convenient storage.
