These 9 oz Plastic Rocks Tumblers (EMI-ST9) by EMI Yoshi are part of the Squares Collection, a line made to put a new twist on the quality and affordable goods that EMI Yoshi is known for. This 9 oz size is ideal as a rocks glass, but also works great for basic drink service and punch. The strong structure of these tumblers makes them reusable, or disposable depending on your needs. Each glass is also fixed with matted ridges on each side for a better grip and optimum sophistication. The square design gives your service that added edge, and can be accentuated with matching square bowls and plates by EMI Yoshi.
