Universal Leakproof Silicone Sleeves

Each sleeve is precisely sized at 7.5 x 3.9 x 3.9 cm and constructed from smooth, flexible silicone that conforms tightly to bottle necks. The material offers balanced tensile strength and recovery — stretching easily over bottle openings yet holding firm under pressure changes, such as those experienced during air travel. Designed for broad compatibility, it fits most standard 30–100 ml cylindrical travel containers used for haircare, skincare, and cosmetics. Its minimalist form factor supports efficient packing, while the non-toxic, odourless composition ensures safe contact with all toiletry formulations. Whether stored upright in a hanging toiletry bag or laid flat in a suitcase, the sleeve remains stable and functional.
