Thank you for viewing! (*≧艸≦) Immediate purchase is OK. This is a set sale (with a bonus ❤️). Please note that we do not sell the step stool separately. m(__)m ☆ Children's Step Stool ☆ With this, children can practice sitting on the toilet by themselves without adults having to lift them! Also, it's great for them to be able to brace themselves. ♡ ☆ Potty Training Seat ☆ It was very useful because you can just place it on the toilet d(ゝ∀・*) I tried various potty training seats, but this one was the easiest to use for me! My child seemed to prefer a character one though... (*uωu*)σ ☆ Overnight Dryness Pad ☆ Bonus ↓ Quoted below ↓ This pad type can be set in cloth pants that your child wants to wear, so you can graduate from diapers quickly and it's economical! It also motivates your child! ☆ Urine Absorption Liner ☆ Bonus ↓ Quoted below ↓ Set one sheet in your pull-up diapers! Even if your child pees, just remove the liner without changing the diaper! Then, just use it as is and the diapers will last longer, reducing the number of diapers used! = Please confirm the following (＞人＜;) = ※ Please refrain from purchasing if you are nervous about used items. ※ We will only accept single item sales if the buyer covers the shipping costs (^^) ※ We basically do not ship on weekends and holidays.
