An Internet Archive copy of Wirefy's own store page for its heat shrink wire connector kits, captured on September 10, 2025, not a live page; on September 23, 2026 wirefyshop.com answered "This store is currently unavailable". The page sells four kit sizes (1080, 540, 270 and 120 PCS) under one description; the SKUs Wirefy-VAR-540 and Wirefy-VAR-270 appear only in the page's product data markup, which is checked separately. The page does not list how many of each connector a kit holds and prints no current or voltage rating.
