There are currently three sizes of magnetic needle holders:
2cm high/4cm diameter with a 1" magnet,
4cm high/9cm diameter with two 1" magnets,
4cm high/13cm diameter with a 45mm magnet
(all measurements are approximate as they are handmade).
All magnets are neodymium disc magnets, and there is a coin with a desired year as a finish in the bottom.
