Approximately 100 pieces are large, about 7cm tall and 6cm wide. About 70 pieces are medium-sized, about 5cm x 4cm. A few smaller ones. I have carefully selected and packed the ones with the best shapes. They were soaked in 60°C water with one bottle of vinegar for 2 hours, then soaked in fresh 60°C water for another 2 hours, rinsed, and dried in the sun for 10 days. They were collected from a pine forest along the coast. There may be some chipping during transportation. Thank you for your understanding.
