As the consummate host, you should never turn away an uninvited house guest. But in the event of a guest who makes it their mission to raid your spirit cupboard, we would like to issue you with some standard equipment: the Combination Bottle Lock.

Place your bottle of spirit in the puzzle and lock it up. The bottle will then be imprisoned in a seemingly impenetrable fortress. Made from stainless steel you can set your own combination and then simply press into the opened bottle and lock. Only you will know how to unlock it and release the bottle. Packed in a full colour gift box with magnetic flip top lid, it makes a rather snazzy gift, too.

Should your drinks cupboard be probed, your last bottle of spirit will remain safe and sound, whilst your thirsty visitor fumes over how to untangle the mess of balls and blocks. If all goes according to plan, they will give up after approximately ten minutes and return home.
