## What is STONE SIGNATURE?

STONE SIGNATURE is an app for designing, previewing, and ordering custom Japanese seals (hanko).

Create a seal that matches your style:
- Enter your seal text
- Try different fonts and seal shapes
- Choose from selected materials
- Browse one-of-a-kind items
- Review a live preview before ordering
- Save your seal ideas in the app and compare them side by side

The app-exclusive save and compare feature makes it easier to keep multiple design ideas, revisit them later, and choose the seal that best fits your style before placing an order.

When you're ready, enter your shipping details and complete checkout securely through Stripe.

STONE SIGNATURE supports both Japanese and English, making it easy to create and order a seal from your device.
