Absolutely. We use the most premium platinum silicone that's non-toxic, BPA free, FDA approved and CA Prop 65 compliant. (Prop 65 standards are among the most stringent standards in place anywhere and are often far more stringent than federal standards).
Shipping is based directly on weight. We used high quality, dense materials in making UniLid. One UniLid set contains 5 lids, and when getting the Kickstarter Special 3 for 2 deal you receive 15 lids. The weight adds up significantly. If shipping ends up being significantly cheaper than our quoted prices - we will certainly take that into account, let our backers know and credit back the difference.
The Food and Drug Administration (FDA) governs the US law for food contact materials. Our silicone has undergone rigorous manufacturing controls which guarantee it meets FDA regulations for materials that are in contact with food.

LFGB is the German standard for testing silicone products that come in contact with food and is the standard for most European countries. The LFGB certification tests are more intensive compared to the FDA testing. Learn more here: http://www.gesetze-im-internet.de/lfgb/ (official German website)
