I ordered 4 of the Sew Stamper heads and I just got around to opening them today. Two of the four were fine, but the Zig Zag stitch was broken. The rubber was either cut or disintegrated. One roll and it fell off the stamper.
I haven't tried the one with the asterisk or snowflake yet.
I'd like to get a new zig zag stamper to replace the old one.
