Great for sublimation. I pressed some with and without the strings. Same result. Definitely recommend using a pressing pillow with scrap paper inside. I pressed 385/60 secsNice color, but a little to thin. We will keep them for now. Price is decent for what you get.Bought the white bags at the request of my granddaughter. I wanted to use them the Cricut Infusible Ink products on them. The bags themselves seem to be of better than average quality and the Infusible Ink worked beautifully. Granddaughter is happy and I’m happy.I have received my order haven't used them for what they were bought for. However, I do like how they feel and look I can't wait until I use them. I'll update when I do use them.I purchased these to carry snacks in the park on our trip to Disney World. The size is good but by day 2 or 3, most of them were falling apart. Literally, the stitching was coming undone and they were falling apart. We we carrying sandwiches, chips, rice kripsie treats, and a bottle of water or Gatorade per bag, to give you an idea of how full or how much weight we were putting in therm. I sublimated images on them and they worked really great for that. All the designs looked amazing. But these arent for everyday use. I was considering selling them in my shop, but I would have to reinforce the seams on them for sure and I'm not sure if thats worth the trouble.Great bag! More see through then what I would like. But it works. Put HTV on them for basketball bags.Great for sublimation! Had to pull out the strings before pressing otherwise they melted but they were very easy to restring. Will definitely be purchasing again!Love the bags! Perfect for sublimation.
