Are these the fabric tubes filled with the gel crystals? If so, I bought some for our WDW trip last August. We used them every day!!! I followed a DisBoard thread on neck wraps at the time - and bought them inexpensively from a woman (Allison Neally) who makes them and was donating her proceeds to the Leukemia and Lymphoma Society. She had some great Disney prints! You may want to search the Dis message boards on "neck wraps" to get more info...
