Review on Pieces Sublimation Shrink Blanks Different by Wayne Ohlrogge

I used this shrink wrap to sublimate glasses. Every time I tried shrink wrap, it quickly melted! Well after 5 toggles I realized it was quality and not a technical or user error as my time and temperature were correct. I had to sublimate a large cereal bowl that used a larger shrink wrap that I buy from another supplier. (transparent film) that was in the oven at 400 degrees for 10 minutes without burning or melting. The photos show my temp was only 325 and I was in the oven for two minutes when it started to melt. 2nd image at the end of six minutes with temperatures reaching 400 degrees. It's too late for me to return them but I wouldn't recommend this product for proper glass sublimation printing without really good tape work! because these glasses are too expensive to rely on poor quality! Try at your own risk.
