I have recently started using crucibles from Nippon Crucible, and I am impressed with the results. The quality and performance of their crucibles are excellent.

The customer service provided by rutsubo.com is also praiseworthy. They are responsive, helpful, and ensure that customer queries are addressed promptly.

Overall, I am satisfied with my experience with Nippon Crucible and would recommend them to others in need of reliable crucibles.
