Frequently Asked Questions

What comes in the set?

Six square silicone stretch lids in nesting sizes, from small to large. Every set includes every size.

What can I use them on?

Square and rectangular containers and meal-prep boxes. Stretch a lid over the rim and the silicone grips the edge. For round bowls, cups and jars, get our Round Stretch Lid Set.

Can I mix round and square in a bundle?

Yes. Round and square sets count together toward the bundle price: 2 sets $29.99, 3 sets $39.99, 5 sets $49.99. Mix any colors and shapes. The discount applies automatically in your cart.

How long does shipping take?

Shipping is free on every order. Most orders arrive within 8–18 days of ordering. You'll get tracking as soon as it ships.

What if they don't work for me?

You're covered by our 30-day money-back guarantee. Email pureprep22@gmail.com with your order number and a real person will sort it out.

How do I get the tightest seal?

Make sure the rim is dry. Silicone grips a dry rim and can slip on a wet or oily one.

Are they reusable?

Yes. Rinse and reuse. They're made to replace single-use plastic wrap.
