LARGE KEYRING MAKING KIT: Included in our set are 60 lobster clasps, 60 key rings with attached chains and 60 open jump rings made from premium zinc alloy iron. Each piece comes in gold, silver and bronze. The clasps are 3.3cm (1.29 inch) in length and 1.1cm (0.43 inch) in width, with an inside length of 1cm (0.39 inch). The keyrings are 2.5cm (0.98 inch) in diameter. Every chain is 2.6cm (1.02 inch) in length, whilst the jump rings measure 6mm in diameter. EASY TO USE AND ATTACH: As there are lobster clasps in our set, you can easily attach your keys to a backpack, wallet, purse or handbag. Push the trigger down to open the clasp to attach or remove it. The keyrings and chains come pre-assembled, so you don't need to thread them onto the keyring. If you do wish to remove the chain, slide it in between the rings on the keyring and remove it. The jump rings come open so you can attach your pendant or key fob and close with a pair of pliers. STURDY AND DURABLE: These key rings, clasps, and jump rings are made from metal which makes them strong, anti-rust, and lightweight. Each keyring has been polished, giving it a shiny appearance, which will look great against your keys. The lobster clasp can rotate 360 degrees, so your charm or keys attached to it are free to move. This will stop your keyrings from getting caught and catching. They are designed to withstand long term use without weakening the opening and closing mechanism. MULTIPLE APPLICATIONS: Our swivel clip and split ring sets come un-assembled, meaning you can use them together or separately. Use these for making DIY homemade resin, wooden laser cuts, or knitted key rings. Give them as a gift for Christmas or birthdays to your friends and family, or use them as wedding favours. Attach them to house, work, garage, shop, car, or motorcycle keys. You can even use this to attach keys, key rings or key fobs to a lanyard, belt or bag. MONEY BACK GUARANTEE: All keyring sets that are sold come with a 100% money back guarantee just in case you are not happy with your purchase. If that is the case, please get in contact with us and we will refund you. Warning! Not suitable for children under three years. Choking hazard.
