Daiso Stamp Pad 4 Colors & Stamp Eraser

DAISO Stamp Pad and Stamp Eraser

?Stamp Pad
(4 colors: Shiny Orange, Honey Lemon,
Cherry Red, Lavender Purple)
Used only once for stamping the marriage certificate at my wedding a year ago.
On the yellow and purple stamp pads, I seem to have accidentally stamped with orange, so the colors have mixed.
I tested all of them today, and the ink still comes out, and the colors did not mix when stamped.

?Stamp Eraser
It has been used a little, and there is more than half remaining.
Dimensions: 10cm (height) x 9cm (width).

Thank you for looking.
