Query: Overpriced but worth having

An excellent though costly kit. The dust brush in a lipstick-like container: extended for use / contracted for storage by twisting the base. Surprisingly handy, and the bristles stay clean. The cleaning fluid and tissues supplied quite good; the microfiber cloth, so-so. I find myself in the field digging out this kit often, taking good care of it because I paid so much, but always having the tools on hand for a cursory to thorough lens cleaning. So I'm happy with the purchase but think it could sell for 60% less and still at a decent profit. Since this is likely the only Swaroksi item I'll ever own, no doubt I've overpaid for the prestige -- and presumably you're expected to as well.
