The Harrows holster and caddy or the Unicorn wooden dropin box will do the trick.
Most of the Bull's Pak series will do the trick but look cheap.
The aluminium cases would do the trick as well - but you have to mess about with the foam inserts cutting them to shape.
The Harrows Royal case, again with some slight adjustments does the trick - and this one will hold a couple of spare shafts and flight.
Until I got my Bonzwa case I used the Harrows holster and caddy and carried a spare set of stems and flights around in one of the Cosmo flight cases
