This is a doctor's set made of felt, including a stethoscope, thermometer, and syringe. Plastic ones can be dangerous or break easily, but these are mainly made of felt and cotton, so they are safe and durable. The part of the stethoscope that listens to the chest sounds has a plastic bottle cap inside. How about this as a gift for children or as teaching material for childcare? Everything is hand-sewn. Please note that the stitches may be uneven, the felt colors may vary, and the amount of cotton may differ. Materials used: Felt, embroidery thread, cotton, string, plastic bottle caps Contents: Stethoscope, thermometer, syringe
