If you mean a mālā for reciting Uvasaggaharam Stotra, I couldn’t verify a specific purchase page for it on JainKnowledge. JainKnowledge does have the Uvasaggaharam Stotra text and meaning, which may help you use the mala properly for recitation. ( jainknowledge.com)

In general, such Jain prayer malas are usually available at:

• Jain temples
• Jain bookstores
• Jain religious item shops

For the stotra itself, you can refer to the JainKnowledge page on Uvasaggaharam Stotra. ( jainknowledge.com)

If you want, I can also help you with the proper Jain way to use Uvasaggaharam mala for jap.
