Food-grade silicone straws support customization  

Colored silicone straws are odorless because the silicone material itself is odorless and non-toxic and does not release any odor. In addition, colored silicone straws may undergo special processing during the production process, such as baking at high temperatures or adding food-grade dyes, to ensure no odor. Therefore, there won’t be any odor to the drink when using colored silicone straws.
