I used only one, but it didn't fit, so I'm selling the rest. The bag has been opened about halfway. They're packed in pretty tightly, so I haven't taken any out, but there are 11 left. The remaining diapers are unused, but please understand this before purchasing. 3L size diapers for small and medium-sized dogs, 12 pieces per pack. - Brand: Petio - Size: 3L - Quantity: 12 pieces - Suitable weight: Under 25kg - Target dog breeds: Small and medium-sized dogs Thank you for looking.
