The blue reusable glass has a lovely smooth round mouth to drink from and the option of a food-grade silicon lid and sip hole to reduce spillage.
They are non-toxic, antibacterial, 100% plastic-free and microwave and dishwasher safe.
Glass fibres are 100% natural and inert. They have been tested and proven to be non-carcinogenic and non-toxic.
Tough and long-lasting, the glass fibres deliver acid, alkali, moisture and solvent resistance surpassing most mineral and synthetic fibres. These are immune to nuclear radiation, UV light, biologic and fungal contamination.
These are glasses that can take the heat and take a pounding. They're stronger and more stable than alternative reusable glasses with mineral and glass fibres, with tenacity that exceeds steel fibres many times over.
Matches perfectly with a Standard or Custom Cuff.
