High-quality stainless steel ice skate blades, Pattern 99, size 8.50" I purchased these used, and they were in very good condition, almost like new. I used them for about six months after purchasing them, but I was injured for about a month, so I didn't actually use them for a full six months. I think these are suitable for children in their growth period. I've only used them a few times since the last sharpening, so they should be ready to use immediately. Screws and box are not included. If you purchase other skating-related items together, I will offer a discount (equivalent to the shipping cost). Depending on the size of the package, I may change the shipping method to Rakuraku Mercari Delivery. - Model: Pattern 99 - Size: 8.50" - Material: Stainless steel Thank you for viewing.
