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 medical-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 when thrown across the room
• XL straw stopper — no pulling the straw through the lid and making a mess
• 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.
