This silicone can sealing lid is made of premium food-grade flexible silicone, with full size 6.3×1.2cm (outer diameter 2.5inch, inner diameter 2.1inch), single net weight 13g. It perfectly fits most standard soda, cola, beer and energy drink aluminum cans. Equipped with reserved air release slits on the top, it balances internal air pressure automatically to avoid liquid overflow while keeping carbonation well sealed. The serrated edge fits tightly on the can mouth to realize dust-proof, insect-proof, leakproof and spill-proof performance. It can preserve leftover canned drinks well in refrigerators, easy to clean and dishwasher safe for long-time repeated use. Multiple fashionable colors are available in stock, and we support Pantone color customization & custom logo printing for bulk OEM & ODM wholesale orders.
