Bondhus Bondhus verschillende - platte zeshoekige sleutelspel/of met 2-10 mm (8U) ondersteuning

So I haven't needed to use my 5mm for like a half year after buying the package, ive just been using the smaller sizes which are great. So I regrabbed my original package and I couldn't find my 5mm, apparently there are TWO 6mm sized keys in there.CHECK your package after receiving so you can send it back if there are things missing/duplicates, not really happy right now as I am missing a 5mm
