I only tried the light blue one once. The others are unused. The images from the third one onwards are from the product website. The following is quoted from the product website: 【Pencil Grip】Supports children to hold pencils correctly and maintain a comfortable writing posture. 【Prevents Finger Calluses】Reduces discomfort in the middle finger with continued use. 【Non-Slip Design】The shape is wider at the top and narrower at the bottom, providing stability and preventing slipping. 【Hollow Design】The hollow structure ensures comfort and breathability. 【Durable Plastic】Made of durable plastic material, it can be used for a long time. Please check carefully for any questions before purchasing. Thank you very much. #PencilGrip #PencilGrip #LearningSupport #WritingPractice #CorrectGrip #PostureSupport #FingerCallusPrevention #NonSlip #Stationery #SchoolSupplies #ForChildren #KidsStationery #EducationalGoods #UnusedItem
