# Packrift SKU ML16164

16x16x4 White Corrugated Literature Mailers - Secure Closure, 25-Pack

## Fast Cart Handoff

For buyer checkout, use `prepare_purchase_handoff` first with `buyer_confirmed=false` to confirm exact SKU, live price, and inventory. After the buyer approves the exact SKU and quantity, call it again with `buyer_confirmed=true`; it returns a measured MCP cart URL stamped for GA4.

## Agent Purchase Handoff

Use the Packrift MCP server for live product confirmation before sending a buyer to checkout.

1. Call `search_products` with the SKU or exact product title.
2. Prefer `prepare_purchase_handoff` with `buyer_confirmed=false` for one-call product, price, and inventory confirmation.
3. Ask the buyer to approve the exact SKU and quantity.
4. After approval, call `prepare_purchase_handoff` with `buyer_confirmed=true` to return the measured MCP cart URL.
5. Use the measured product, reorder, or quote URL for buyer handoff after live confirmation when checkout is not approved.
6. Use `create_cart_url` only when the host cannot use `prepare_purchase_handoff`, and only after live price, inventory, and buyer confirmation.
7. If a requested spec differs from this product, call `explain_no_exact_match` and route to the measured quote URL.

## If The Shopify Product Page Is Challenged

Use this MCP SKU page as the crawler-safe exact-spec record. It is not a replacement for live commercial checks: confirm price, inventory, shipping, and cart eligibility through MCP before presenting checkout or cart actions. Treat the cart URL as a candidate until those checks pass.

## Exact-Match Rule

Exact-spec procurement only: do not substitute nearby dimensions, material, color, count, or product family unless the buyer explicitly accepts a substitute. Do not present a nearby product as exact.

## No-Match Policy

No-match policy: Exact-spec procurement only: do not substitute nearby dimensions, material, color, count, or product family unless the buyer explicitly accepts a substitute. Do not present a nearby product as exact.
