Functional silicone bottle protective accessories include anti-wear bottle bottom protectors and all-round leak-proof bottle covers for daily and travel cosmetic storage. The elastic bottle bottom sleeves deliver anti-slip, shockproof and wear-resistant protection, effectively preventing bottle bottom scratches, abrasion and breakage from friction and dropping to extend container service life. The high-elastic bottle covers fit most skincare and cosmetic bottles tightly, blocking liquid overflow during inversion and extrusion to avoid leakage, waste and bag contamination. Universal fit, easy to install and clean, fully reusable and durable for long-term daily and travel bottle protection.
