If you're into tumbler crafting, this makerflo 25-pack is an absolute game-changer! You get 25 seamless 30oz skinny tumblers that are perfectly designed for sublimation - no ridges or seams to interfere with your designs. The double polycoat application ensures vibrant, long-lasting prints whether you use a heat press or conventional oven. Made from BPA-free food grade 304 stainless steel, these tumblers are completely safe for drinks and won't leave any metallic taste. The double wall insulation keeps drinks cold for hours while preventing condensation so the exterior stays dry and easy to grip. Each tumbler comes with a splash-proof lid and straw, making them ready to use right after crafting. The rimless bottom design looks sleek and makes cleaning easy. They're perfect for creating personalized gifts for birthdays, holidays, anniversaries, or any special occasion. The instructions are clear - 375°F for 6 minutes in the oven or 365°F for 40 seconds in a cup press. With 25 tumblers in the pack, you can create a whole inventory of custom designs or split them with fellow crafters. The quality is seriously professional-grade, much better than those cheap thin tumblers that dent easily. Whether you're a serious tumbler business owner or just enjoy DIY crafts, this pack provides amazing value and consistent results that will make your creations look store-bought quality!
