This material is not toxic and does not contain odor or BPA. We choose this silicone material because it will make it impossible against any damage or cracking when putting the tray in the zer. It will be firmly fixed to prevent the lid pouring and absorption of odors. Put the lid on top of the tray and fix it, open the filling port and start filling. After the tray is filled with water, please make sure that it is tightly closed and place it in the zer. Remove the lid when it is ready to use without fear of shedding. The funnel can also be a great use to transfer home canned, liquids or dust. Note: Due to the light and screen setting difference, the item's color may be slightly different from the pictures.
