I been collecting them from time to time. Maybe because I can't carve as detail as these.
The small match box stamps are one of my favorite stamps now. The stamps are carved in full detail and very small. I use the "Merci" (Thank you in French) rabbit stamp + lace stamp and stamp them in a small piece of "Thank you" card for my customer who have brought things from me. It makes a smile of my face and hope it brings my customers too :)
