うっかり硬いものを噛んだり、舌を切ってしまうのが心配な方へ, 柔らかいシリコンは金属のより安全な代替品です (またはガラス). A silicone straw is less likely to get uncomfortable hot or cold since silicone doesn't conduct warmth as efficiently as metal does.
You don't need to be concerned about chemicals escaping into your beverages when using these straws because the FDA has authorized silicon as a safe material to be used in any form of food or drink equipment.
