Unique design with stainless steel stiffening ring that prevents the sink from collapsing when full Base is broader than top so it won’t tip over in use Fine to use with hot water (60°C) and detergent Fully taped seams Wide webbing carry handles Comes with its own handy zippered storage pouch with drain hole The 5 Liter size makes an excellent dog bowl Proper Use: Please note: bleach (even in mild concentrations) will damage the polyurethane coating and nylon fabric and should not be used Always start with cold water in the sink, then add hot water (very hot water by itself will damage the seam tape)
