Most of you probably haven't heard the word Borosilicate glass before (unless you read our old blog post "What is Borosilicate glass?").
Borosilicate glass is the material seastraws are made out of which makes our straws quite durable for being a glass product.
We've explained what Borosilicate glass is in a previous blog post. However, we recently found this fairly 'easy-to-understand' youtube video which explains what it is PLUS how it's manufactured.
So, if you want to nerd yourself into this simply watch this 6-minute video instead of spending that time on Instagram.😉
