This Tumbler Cup cozy is designed to fit most 40oz tumbler cups with a handle. It has a button to keep the cozy on the cup and is crocheted with a beautiful jasmine stitch pattern. Custom color, or surprise color optional. You can also add a fun surprise patch to your cup for an additional $2.50. To add the patch please tell me a little about yourself and what you may prefer in the personalization box and I will pick one accordingly.
