Review on 2 Pack Of White 450Ml (15.3Oz) Lotion Pump Bottles - Empty Soap Dispenser For Bathroom, Kitchen, Shampoo, Shower Gel, And Hand Sanitizer by Star Bell

I would first like to say that one of the bottles came dented and cracked so I was only able to use one of them.The large bottle has a 33/410 pump size (very hard size to find) and the small a 24/410 pump size. If you are wanting to put labels on these bottles, the large has a 4.25" x 2.25" flat surface and the small has a 2.25" x 2.25" flat label surface. They are a very hard plastic and don't have any give to squeeze a product, so any caps would have to be a sprayer or a pump. Hope this helps.
