This cute tumbler charm is perfect for any mama. It is a perfect way to dress up your favorite tumbler. You can also use this on your favorite insulated coffee mug with a handle approximately 2.5 inches tall. It is easy to attach, simply unscrew the clasp, slide through the handle then reattach the clasp. If the clasp is hard to reattach you may need to pull back on the beads a little bit. Due to the nature of the beads it is not recommended that yo put this in the dishwasher but it can be washed with soapy water.
