Bulk item; we removed from larger kits so consumers can buy individual parts at lower prices. This means there is no retail packaging included and we stored them in open containers so they are not considered in sterile condition and should be washed prior to use.

You will receive what's pictured: 1 diaphragm with white o-ring.

Medela and Harmony are registered trademarks of Medela Holding AG. Our company is not affiliated with Medela and items are taken out of larger Medela kits while wearing gloves. We are not authorized resellers or distributors of Medela. Any warranty is likely void when buying at a discount here, but our company does offer a refund policy.

Thank you!
