Chiba-bogu are one of the best online retailers of kendo equipment. However in the past all their equipment was very expensive. Now with the launch of their new site, they have a few new bogu including the one pictured above, their 5mm Clarino model.
Clarino is an artificial deer-skin substitute that performs very well. Most often it is used for kote palms, but here it is used for all the edging as well.
The advantage with this bogu is that it is order made to your measurements so you can be assured of a good fit. It does mean that it takes 6-10 weeks to complete your order. But it appears to have been marked down from over $1000 to around $650, which is pretty good value.
