ECOtanka Grail 350ml Double Walled Cup




ECOtanka Grail Cup 350ml has been designed and moulded to the shape of a wine glass, which makes this a comfortable style cup to hold. The inside layer follows the design of a wine glass with its curved oval shape bottom, unlike other similar products.

Our advanced food-grade ceramic coating on the inside of the Grail adds to your drinking pleasure and allows you to keep the taste and quality of your wine. Adding wine to any stainless steel finish can affect the taste and in some cases can completely change the quality and flavour. 

The ECOtanka Grail is double walled is made of 304 stainless steel on the outside and inside. 

The ECOtanka Grail is suitable for most drinks both hot and cold due to is double wall design and ceramic coating giving it vacuum like properties. This cup is ideal around the pool, camping, travelling, for a special occasion and is dishwasher safe.

The Grail inner coating has been tested for BPA, BPS and other chemicals from an independent testing lab, see below for the test report.




Inner Ceramic Coating

​​​​​​​The ECOtanka Grail 350ml Stainless Steel Cup has been coated on the inside with an advanced food-grade ceramic coating that has been fully tested.  The Ceramic Coating adds a lot of extra benefits to the cup, with one standout benefit being the ability to have red wine in a stainless steel cup without losing the flavour and quality.   The inner coating also stops the heat transfer going to the outside layer which allows the cup to be used with hot drinks. 







Custom Logo Printing




Custom laser logo printing is available for the ECOtanka Grail to have your business logo printed on the cup or to personalise for a special event.  Your laser printing on the cup would be either a laser "white" or "black" and this will never come off.    View the custom logo printing requirements​​​​​​​

​​​​​​​ECOtanka values quality. In order to make sure that our products are 100% safe for you to use and long-lasting, we carry out a material test every 5 years by an independent third-party lab.  All parts of ECOtanka products that come in contact with your liquid or food are tested.  

The materials we test are as follows:
- Stainless Steel for Cup material
- Inner Ceramic Coating Paint

Our testings are mostly as per EU standards. From time to time, we carry out FDA testing as well.  As testing samples, we provide one product type for each material category. 

All material batch orders are tested within the factory and all individual orders are self-tested by our own team in China using two methods as follows:

1. A stainless steel liquid colour test to confirm the stainless steel type.
2. A spectrometer test which takes an analysis of the material makeup to verify its quality.
