The Seashell Straw Cup

Meet The Seashell Straw Cup — designed by parents, trusted by Littles. The safest, most innovative straw cup on the market.

Made from pure European-grade nontoxic silicone — the very first of its kind in the U.S.

Unlike standard “food-grade silicone,” our silicone:

• Has zero fillers or plastics
• Has zero PFAS, BPA, BPS, PVC, and phthalates
• Has zero Lead, Teflon, and other hidden toxins

Just pure, buttery-soft silicone that feels good in little hands and keeps parents worry-free.

Every detail is built for real life with kids:

• The tightest snap-fit lid on the market — no messy explosions
• XL straw stopper — no pulling the straw through the lid
• Weighted straw design — angles upward when dropped to prevent drips
• 4.5 oz capacity — perfect for Littles ages 1–5

Seamless, dishwasher safe, and built to last — because the last thing parents need is another flimsy cup that doesn’t hold up.

• Child-Safe Materials: Made from pure European-grade silicone, the first of its kind in the U.S. Exceeds the strictest standards in the US, California, and EU. Free from fillers, plastics, PFAS, BPA, BPS, PVC, lead, Teflon, and phthalates.
• Easy to Clean: Seamless one-piece construction with removable straw. Dishwasher safe and odor-resistant for everyday use.
• Mess-Free Design: The tightest snap-fit lid on the market — no child can pop it off, no messy explosions.
• Straw Security: Built-in straw stopper so Littles can’t pull the straw through the lid.
• No-Drip Weighted Straw: Weighted design angles straw upward when dropped to limit puddles on the floor.
• Perfect Size: 4.5 oz capacity, thoughtfully designed for Littles ages 1–5.
• Maximum Durability: Premium thickness and shore hardness ensure this cup withstands years of use.
