Some foreign substances, such as black dots, may be present due to the nature of the manufacturing process. Thank you for your understanding.
Scrape marks resembling grazes may be visible on the base due to the manufacturing process, but they are not considered defects.
While nanazero's fins are inspected to conform to the fin manufacturer's standard size before shipping, in rare cases, they may be difficult to fit due to compatibility issues with the fin box, or the fins may wiggle if the box is too large.
If the fins do not fit, do not force them, as they may become stuck. Instead, adjust by gently scraping the bottom of the fin with sandpaper.
If the fin wiggles and does not sit securely due to the fin box being too large, adjust the base thickness by applying aluminum tape for stability.
Fins made of hard materials can cause injury upon contact. Please exercise caution to avoid contact with people during wipeouts. If the fin tip is sharp, rounding it with sandpaper can help prevent injuries.
