High quality, durable 3mm neoprene foam. You will notice the value difference when you open the box and feel the soft fabric in your hand. Scuba knit polyester fabric is laminated to the outside of the neoprene to provide a surface suitable for heat transfer vinyl (HTV), screen printing, sublimation, and fabric markers. Use SVG graphics with your home vinyl cutting machine to print perfect sleeves every time. The inside of the sleeve is lined with a polyester mesh layer that applies just the right amount of friction to cans. Stitching on the thermocoolers includes a reinforcement reverse stitch to ensure durability. Our insulating blanks are perfect for promotional events, craft parties, and home personalization. Common events where they are seen: birthday, anniversary, wedding, bachelorette, bachelor, graduation, and celebration. Make promo, funny, and party favor designs easily. Create fun gag gifts for every occasion. You can also use them as a simple cup or beverage cover. The bottom acts as an absorbent coaster. Thick thermal insulation on our can coolers allows for the most versatile fit, and they keep your drink ice cold.
