I bought these one-touch snap fasteners at Daiso. There are 4 sets of 13mm snaps per bag, and I have 4 bags. They are white, ivory (2 bags), and navy. I'll also include the remaining half-used pink and white snaps as a bonus. No special tools are needed, so you can use them right away☆ I will put them in an OPP bag and ship them via Yu-Packet Mini. Thank you.
