This cute charm is the perfect Spring or Summer accessory for any special Grandma. It is the perfect accessory for your favorite tumbler or insulated coffee mug. If using on a coffee mug the handle needs to be approximately 2.5 inches high. It is easy to attach, simply unscrew the clasp, slide through the handle and then reattach the clasp. If the clasp is hard to reattach you may need to pull back on the beads a little bit. It is not recommended that you put this in the dishwasher but it can be washed with soapy water.
