Child Cup Egg One unopened bag and One opened bag (3 used, 7 remaining). This product allows you to start allergy checks from whole eggs. It's easy, just mix it into baby food. I ordered it from Rakuten, but it arrived late, so we didn't use much of it, and I'm offering it for sale. The expiration date is 2027.05.08. * Shipping is unavailable from December 31st to January 6th. Thank you for your understanding.
