If you think you need 1 .............. GET 8! So many uses for a capped 4 oz. plastic squeeze bottle. And when they are sturdy as are these from this seller, go crazy with what you put in them. Buy the huge bottle of dish detergent and fill up a nice small 4-ouncer to keep right IN the kitchen sink at the ready. How about some peroxide in another one to keep handy for laundry stains? Little bit of your favorite balsamic vinaigrette left over? Yep, you go it. The caps are very secure which is a bug plus too. Over all, very satisfied with this versatile, well-made product provided by an efficient and professional seller.
