I gave birth in 2023 and used this for about a year. Please see the third photo for how to use it! You can also find lots of information online, so please take a look ⭐︎ I've also used Milton, but I personally found sterilizing in the microwave easier! I washed it thoroughly with detergent, but there are some water stains remaining. Other than that, it's in good condition and I think it can still be used. Thank you! As a bonus, I'll include a box of powdered milk ⭐︎
