The CAO MX2 come in a tin of five daggers that is about the same sixe... maybe too short fer you... Check your B&Ms selection of flavoreds and what not... you may find what you are looking for.
Another option would be to snag some smaller cigar tubes and tape or JB weld three together (middle one facing the opposite direction... could be a fun project for a DIY-er... (they'd be a sealed invironment too)
Just throwing out some ideas. Good luck.
