Thank you for viewing! This is a popular drop-in toy that children love♫ ⭐︎ There are 15 drop-in pieces. Two plastic bottle caps are glued together, and rice is inside, so they make a shaking sound. The surface is protected with clear tape, the sides are secured with cellophane tape, and then wrapped with colored vinyl tape. Also, the size of the drop-in pieces may vary slightly depending on the size of the cap. ⭐︎ Each drop-in piece is handmade, so there may be slight misalignments, distortions, wrinkles, dust, or stains. Thank you for your understanding. ⭐︎ The backs have marks on checkered origami paper. ⭐︎ The case is made of a soft silicone material. The cut edges are reinforced with clear tape from above. Please check the photos. Laminated animals are attached to the lids with double-sided tape. There may be air bubbles, wrinkles, or dust, but please understand. m(._.)m ⭐︎ Since children may put them in their mouths, please be careful of accidental ingestion and always supervise them. ⭐︎ During play, the tape may peel off or dust may accumulate, so please wipe them with a wet wipe or reinforce them with tape as needed. Since everything is handmade, thank you for your understanding. ⑅︎◡̈︎* 4
