Thank you for viewing! If you'd like 30 sets, I'll accept your offer immediately! I bought these buttons intending to start making handmade items, but I haven't gotten around to it, so I'm selling them♡ They can be used for bags, pouches, small cases, baby bibs, and drool pads for baby carriers. T5 buttons: 12.4mm diameter Color: Black (Also available in white, pink, blue, purple, khaki, skin tone, navy, gray, and watermelon) ☆You will need pliers (hand press) to attach them. I still have about 900 sets, so please let me know if you'd like to purchase more than 30 sets♪ I also have other handmade materials for sale. You can view them all from the link below. I will offer a discount for multiple purchases. I would be happy if you would take a look♡ #ShanshanHandmade I also sell baby clothes and baby items. I will offer a discount for multiple purchases.
