This cute cute charm is the perfect accessory for any Mama. Use it on your favorite tumbler or insulated coffee mug. It attaches easily, simply unscrew the clasp, slide through the handle and then reattach the clasp. If it does not reattach easily you may end to pull back on the beads a little bit. It is not recommended that you put this in the dishwasher but I can be washed with soapy water.
