Review on Bondhus 18099 Bondhex Color 5Mm 10Mm by Paul Wilson

I had a set of metric and standard hex keys that I wanted holders for. I have this and Bondhus standard size. The standard size seems to encompass most hex key sizes in this range, but the metric does not. Missing sizes are 4.5mm, 5.5mm and 7mm which I have allen wrenches for. This is also not an uncommon size. So disappointed with it.
