This cute tumbler charm is perfect for anyone who loves coffee. Use it on your favorite tumbler or travel mug with a handle height of at least 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. It is not recommended that you put this in the dishwasher but it can be washed with soapy water.
