Just like the ones that come with our Knitter's Block Kit, these will not rust! They're also handy for temporarily pinning sweater parts together (but be careful if you try it on!).
Tin of 40 Stainless Steel T-pins
**Please beware of non-stainless steel t-pins as they may rust when exposed to water and may damage garments. Stainless steel t-pins DO NOT stick to magnets. You may also test them by placing a couple of t-pins in a saucer of water overnight. When you remove them the next day, you should see no signs of rust.
