I received a pair of CS, a ballpoint 95 and a fountain pen 150. I love these models, esp. the ballpoint. And folks, I need your help....... For the ballpoint, I can't fine the refill in Hong Kong, I tried many similar refills but the metal points are too big that cannot be used. Any recommendations for getting any compatible refill anyway? I saw a thread here below saying that 2 refills may fit. https://www.fountainpennetwork.com/forum/topic/342875-a-vintage-conway-stewart-ballpoint/?hl=%2Bconway+%2Bstewart+%2Bballpoint Anyone tried before?, as I need to order form Cultpens and if the model doesn't fit, then the $$$ is gone... For the fountain pen, the sac is broken and the original metal cover is rusted and so the seller used a silicon sac instead. Now the pen cannot be washed and the ink is difficult to be filled. Any recommendations that I can find a replacement? Thank you very much for your opinions..... ^_^
