Review on Go Green with Rolling Sands 24oz Drink Bottles - Set of 3 for Eco-Friendly Hydration by Kelly Johnson

Be very careful with the heat! Do not wash in the dishwasher (as instructed in the instructions) and do not place near other heat sources. The plastic is very thin. I bought them for a client in both green and black (which is more of a dark gray because it's translucent). They didn't want to spend a lot on promotional items so they worked per piece and we can order in smaller quantities. We applied the logo to it with professional grade vinyl and often we can use a blow dryer or heat gun to further secure the vinyl. Do not do that! I didn't think they were that sensitive to a hair dryer, but one of them quickly deformed. So far they have served their purpose. We just don't use heat to set the vinyl, which isn't necessary anyway.
