William Morris Seaweed Marine 12oz Ecoffee Cup, a reusable cup made with natural bamboo fibre – one of the world’s most sustainable resources.
It’s BPA and phthalate free and at just 135g, it’s light, sturdy and fully dishwasher safe.
Dishwasher safe - both cup and silicone parts are safe for the top shelf, just remove sleeve and lid prior to dishwasher.
Not microwave safe as it can mis-shape
Designed more as a on-the-go cup rather than a cup to keep drinks hot. We found that these retain a good heat for about 30 minutes.
Although these do have a tendency to stain, apparently you can use a paste of baking soda to remove stains if they occur.
Not unbreakable! They can crack if you drop them so treat them with care
Ecoffee Cup is BPA and phthalate free.The cup is made from organic bamboo fibre, corn starch and resin binder. The lid and sleeve are made from pure food grade silicone. Silicone is a combination of silica (sand) and oxygen. They contain no plastic or latex.
