母乳クーラーバッグ用保冷剤

I was skeptical this tiny pack would last a full day, but it slipped right into the cooling cup and kept my milk icy even after a long work shift. The fit for both 16 and 25 oz coolers means I swap it between my pump bag and travel cooler without a struggle.

It fit snugly into both my 16 oz. and 25 oz. coolers, so I didn’t have to panic about which bottle I was using that day. Kept things properly chilled the entire 24-hour window, even after a long shift.

Kept my milk cold through two 12-hour shifts and a long commute home, even after I opened the cooler a few times. It slid right into the 25 oz. model without any fuss, so I'll be grabbing a second one for my work bag backup.
