The Cog Rod & Trinity Cog 用 交換用ジョイナーピン（スペア）

My Trinity Cog was useless after one pin snapped, so I ordered a fresh pack and the fit is perfect—they click in snugly and hold tight during fidgeting. Glad these replacements are available instead of buying a whole new fidget.

These little pins are a lifesaver when you inevitably lose one of the originals mid-fidget. They click in snugly and hold the cogs together just as firmly as the ones that came with the set, so my Trinity Cog is back in action.

Finally, a pack of spare joiners that actually fits the Cog Rod and Trinity Cog without any wobble. They snap in securely, so I don’t have to worry about losing a piece mid-fidget again. Having extras on hand has saved me from buying a whole new set.
