### What to expect with FCML
FCML travels through USPS letter mail rather than as a standard package. Because of this, tracking works differently:
* Tracking updates may be limited, or [USPS.com](http://USPS.com) may show no details for your shipment
This is expected and does not indicate a problem with your order. You can still check your order status and delivery confirmation directly in Palmstreet.
FCML shipments typically arrive within **1–5 business days** after the label is purchased.
### Which orders qualify for FCML?
FCML is available when both of the following conditions are met:
* The item belongs to an eligible category: **Trading Cards, Sports Cards, Stickers, Coins, Disney & Loungefly, Sports Memorabilia,** or **Collectible Toys**
* Total shipment weight is **3.5 oz or less**
### How to buy FCML label
When fulfilling an eligible order on the Order Fulfillment page, enter the package weight and dimensions to confirm eligibility. If the order qualifies, USPS FC Mail Letter (FCML) will automatically appear as an available shipping option.
**USPS FC Mail Letter**
* Weight: must be 3.5 oz or less
* Dimensions (L × W × H): Not more than 11-1/2 inches long, or more than 6-1/8 inches high, or more than 1/4 inch thick.
* e.g. 1 oz, 10 in × 6 in × 0.25 in
**USPS FC Mail Flat**
* Weight: must be 3.5 oz or less
* If a mailpiece exceeds any of the maximum dimensions for a letter, it is classified and priced as a flat (large envelope).
* e.g. 1 oz, 10 in × 6 in × 0.5 in
### Important: FCML labels are non-refundable
Once an FCML label is purchased, it **cannot be cancelled or refunded**, even if unused. Please confirm all shipment details before purchasing.
FCML shipments also do not support:
* Shipment insurance
* Signature confirmation
### Add a preset of FCML on seller hub
Shipping presets can be configured and applied directly in Seller Hub. Follow these steps to set up and use presets effectively:
**1.** Navigate to **More actions > New shipping preset** at the bottom-right of the **My orders** page.
**2.** Select **Add preset** and input frequently used shipping details such as weight, dimensions, and delivery service. **Note:**
* The first preset created is automatically set as the default.
* Additional presets can be manually set as default.
* Up to five presets can be saved to accommodate different shipping needs.
