Redfly travel toiletry bottles, 3 oz

A wide opening makes these silicone travel bottles easier to fill with thicker toiletries and to clean inside, which is useful when you want to take your own shampoo or conditioner rather than rely on small hotel bottles. The set is listed as four refillable 3 oz containers, with a clear zippered bag for storage and travel. It also has dispensing valves, side grooves for labels and a three-layer leak-resistant design. Those details make it a practical format for separating everyday liquids, though the listing does not recommend oil-based products.
