Approximately: Height 15 cm, Width 27 cm, Depth 10 cm (excluding the drawstring portion) The inside uses washable aluminum insulation/cooling sheet. I started making these as part of my child's kindergarten preparation and got hooked on handmade items! I try to sew carefully, but as a handmade item by an amateur, there may be some loose threads or crooked stitching, so please understand. Please refrain from purchasing if you are looking for perfection or are overly sensitive. It will be shipped folded, so there may be some creases!
