A: Yes, this product should be used with other water based products.

**Q: Does this product come with measuring device?**

### ⭐⭐⭐⭐⭐ Yard die
*by A***R on January 16, 2026*

Works great

### ⭐⭐⭐⭐⭐ Comparable to Blazon.
*by M***. on October 5, 2025*

Comporable to Blazon without the high price. Similar dilution and fading rate. If you need a high quality indicator dye that won’t fade immediately, but will fade over a week here it is. Container jug is easy to handle and pour.
