To use the Playgo Toys Gourmet Burger Cart set, simply take out the included pieces and let your child start creating their pretend burgers. They can stack the buns, add patties, cheese, and veggies just like a real chef. For cleaning, use a damp cloth to wipe down the pieces. Make sure to dry them thoroughly before storing. Keep small parts away from children under 3 years old to avoid choking hazards. Store the set in a cool, dry place to keep it in good condition for long - term use.
