This super cute tumbler charm just screams Spring! It is the perfect way to add some color to your favorite tumbler. It 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 it is hard to reattach you may need to pull back on the beads a little bit. The charm is made with silicone beads, metal spacer beads and a sturdy cable wire. Due to the nature of the beads it is not recommended you put them in the dishwasher.
