This cute charm is perfect for any Mama. Dress your favorite tumbler up for spring. This can also be used on your favorite insulated coffee mug with a handle height of approximately 2.5 inches high. It is easy to attach, simply unscrew the clasp, slide through the handle and reattach the clasp. If the clasp does not reattach easily you may need to pull back on the beads a little bit. This is made with silicone beads, plastic spacers and a sturdy cable wire. It is not recommended that you put this in the dishwasher but it can be washed with soapy water.
