The Slotted Lid for Wide-Mouth Mason Jars Provides Secure Ticket Drops. This Insert Fits Seamlessly into the Lid Ring, Replacing the Standard Sealing Lid. It Allows Users to Insert Standard-Sized Tickets While Keeping the Jar Closed from Unauthorized Access, Including Pieces of Paper or Other Items. The Coin Slot Feature Enables You to Capture Loose Change in Your Mason Jar. Background: A Food Contest Required Secure Ticket Drops, as Judging Was Based on the Number of Tickets Received. To Prevent Tampering and Ensure Fairness, a Custom Solution Was Needed. Instead of Cutting Holes in Existing Lid Inserts, a Slotted Lid was Created to Meet This Need.
