Use the selected variant's `id` for checkout. The product's `id` is a different identifier. Read the price from `variants[].price.cents` and the currency from `variants[].price.currency_iso`. All ten variants were USD 45.00 on 2026-10-27. Fetch the feed again when preparing a purchase; current prices and variants come from the feed.

The product price excludes shipping and tax. Checkout confirms the selected variant's availability and the final total.

## Choose a size

These are garment measurements from the product's supplier size guide, checked on 2026-10-27. Compare them with a sweatshirt that fits the buyer. Width is measured flat across the garment, under the sleeves; it is not chest circumference. Length is measured from the high point of the shoulder beside the collar to the bottom hem. Sleeve length is measured from the shoulder seam to the cuff.

| Size | Length (in) | Width (in) | Sleeve (in) | Length (cm) | Width (cm) | Sleeve (cm) |
| --- | ---: | ---: | ---: | ---: | ---: | ---: |
| S | 27.5 | 25 | 22.5 | 70 | 64 | 57 |
| M | 28.3 | 26.5 | 23.3 | 72 | 67 | 59 |
| L | 29.3 | 28.3 | 23.3 | 74 | 72 | 59 |
| XL | 30.3 | 30 | 23.3 | 77 | 76 | 59 |
| 2XL | 31.3 | 32 | 23.3 | 79 | 81 | 59 |

The listing describes an oversized fit. Fourthwall's supplier guide also includes a "runs small" note and advises ordering one size up. Use the measurements to choose the intended fit. The supplier allows measurement differences of up to 2 inches (5 cm). The current guide is available through the product page's **Size guide** button.

## Prepare checkout

Construct this URL with the selected variant UUID and a positive integer quantity:

```text
https://shop.faba.run/cart/checkout?products=VARIANT_UUID:QUANTITY&currency=USD
```

Replace both placeholders. For one sweatshirt, use quantity `1`. For several variants, separate the `VARIANT_UUID:QUANTITY` pairs with commas. [Fourthwall's endpoint reference](https://docs.fourthwall.com/shop-apis/cart-checkout-endpoint) describes the format.

Opening the URL creates or updates a cart and redirects to Fourthwall's hosted checkout at `https://shop.faba.run/checkout/...`. Confirm the product, color, size, quantity, and price in that checkout. A redirect to the shop homepage means checkout was not prepared; recheck the current catalog and selected variant IDs before retrying.

## Complete the purchase

Shipping details and payment are entered in the hosted checkout. Check the final total, including shipping, tax, and any displayed import charges, against the buyer's budget before placing the order.

If your client cannot complete checkout, return the prepared checkout URL and state that payment is still pending. Report an order as placed only after Fourthwall confirms it and supplies an order number. A checkout link alone is not a completed purchase.

## Shipping and returns

Fourthwall prints and ships the sweatshirt to order. Shipping charges, destination availability, and delivery estimates are shown during checkout.

General returns and sizing-related returns are not offered for these made-to-order products. Print errors and visible quality issues are eligible for a replacement or refund under the shop's policy. Use the [contact form](https://shop.faba.run/contact) for order help. Read the full [Returns & FAQ](https://shop.faba.run/pages/returns-faq) for cancellations, quality issues, and other conditions.
