# Acrylic keychains

> Choose a small or large two-sided acrylic keychain.

Acrylic keychains are one family with two immutable size variants.

| Product ID               | Physical output    | Required front and back ratio |
| ------------------------ | ------------------ | ----------------------------- |
| `acrylic-keychain-small` | 1.5 × 1.875 inches | `4:5`                         |
| `acrylic-keychain-large` | 3 × 2.125 inches   | `7:5`                         |

Both `front` and `back` are required once and have fixed orientation. Prepare
the two sides independently. Do not combine them into an `artwork` asset.
