2-pack of boil-over protection at a good price. Convenient and smart boil-over protection that prevents your pots and pans from boiling over. Just put the lid on and it will never boil over, thanks to the smart \"flower\" in the middle that releases steam and catches anything that might try to boil over. Never overcook rice or similar again. Works for all pots with a diameter that is a few cm smaller than the size of the boil-over protection. The boil-over protection is made entirely of silicone for kitchen use. It does not absorb taste or odor and can be put in the dishwasher for easy cleaning. It is also oven-safe up to 230 degrees and down to -40 degrees. Always use instead of a regular lid when cooking! You \"can\" adjust the heat by adjusting the flower to release some steam (or none). Available in gray with a light gray/blue flower or yellow with a green flower. Colors (3 choices) - 2 gray, 2 yellow, one of each (gray, yellow) Size - Diameter 30 cm (34 cm including handle), fits pots up to approx. 28 cm Material - Food Grade Silicone (BPA free) Quantity - 2 pcs
