Hello Kath,
Thank you for contacting me. I am afraid there is little information about the ring pen holders for cutlery and I think it would be a case of trial and error.If you buy from an online seller who will accept returns then you won’t waste money if your Father in Law found he couldn’t use them. I am sorry to not be of more use to you.
Hi Caron,
I was hoping you could perhaps tell me if there is anymore info on the Ring pen ultra for use with cutlery.
I think my father-inlaw could really find these helpful.
Many thanks
