Hi Thank you for the feedback. With the standard name stamp it comes in one size but there are loads of different font style and font size options you can try! We don't guarantee the ink is permanent but it has been tested independently by a laboratory and will work on most fabrics. For best results the fabric must be flat and smooth. It won't work on fabrics with a thick stretchy weave such as socks, fleece and polo shirt material.Best wishesFrancescaÂ
“They are clear, and easy to use. My main issue was writing with a sharpy, makes their name illegible, but the stamp keeps their names clear and readable.”
“Fabulous - super quick service, great product. I keep telling everyone at school just how useful the stamps are - I even stamp my daughters swimming goggles :)”
