This bookmark would be a great encouraging Christian planner gift bookmark or reader gift. It has a 37mm x 24mm charm with a single mustard seed at the center. It would be a great reminder of the scripture of Matthew 17:20 that tells us that with only a very small amount of faith, we can move mountains. The bookmark measures approx. 4.6 Inches in length. This item contains small pieces and is not intended for children under the age of 14.
