Will my ToMA glass straws break?
Our laboratory-grade borosilicate glass straws are much stronger than the soda-lime compound used in typical drinking glasses. (Take a look at this 20-second video.)
Of course, any glass can be broken or chipped if dropped from a height or onto a hard surface, but in our months-long tests, we saw very little breakage. Simply handle your glass straws the same way you would handle your other glassware.
