The magnets must be glued into holes using a superglue or different strong glue. Since there's not many fishing accessories i came up with an idea for a box where i could store my leaders for method feeder. Box contain 4 inserts which can hold few 10 cm long leader for method feeder. It is secured with bigger magnets holding the lid as well as smaller ones holding the inserts. Logo made with help of chat gpt :D It's one of first models which will be upgraded in the future. Hope You enjoy it.
