Warranty

Manufacturer warranty (source market)iThe maker's warranty period for the exact SKU or configuration and market named in the source note. It applies only to that stated market, not every regional variant. Statutory consumer rights are excluded. The base term is stored. An extension that needs registration goes in the source note.

1.5years10Maker product pagemyearfun.com/warrantyRead 8 October 2026Selected global direct-store quality-defect warranty is eighteen months from purchase. Optional registration extensions and Japan-specific terms are not included in this base value. A generic page banner says Lifetime Warranty, but the specific quality-defect policy and product warranty card explicitly state eighteen months. The specific policy governs this stored value.
