Review on 📦 Premium Sublimation Shrink Sleeve Tumbler Transfer Packaging & Shipping Supplies: Ensuring Optimum Protection and Delivery Excellence by Andrew Walton

I bought these jacks with some trepidation. I've read various posts about fusible sleeves. I did a little research on temperature and timing and decided to try the lower recommended settings first. I sublimated onto a thin glow-in-the-dark glass which I wrapped in parchment paper (instead of meat paper) before shrinking the wrapper. I placed a piece of parchment paper on the air grill, 300 degrees for 4 minutes, turning once in the middle. No case melting. It came out perfect! This was my first attempt and WOW! I look forward to using this product for my niece's bridesmaid gifts.
