Tip Set for Glassline Pens

I have lost and/or broken the fine pin for the fine nib. The nibs are blocked and I cannot find pins to unblock them. Please tell me where I can get a supply of these fine pins as all my fine nibs are now useless. Apart from this niggle I love using this product.

Warm Glass UK - we find that that a staple from a stapler works great (mini staples for the finest nib) also pins and fine needles work.
