The RodioCraft .5g Blinde Flanker spoons are slightly smaller than the now-discontinued Daiwa .4g Vega spoons. The Blinde Flankers are 20mm long and 8mm wide. The Vega spoons were 23mm long and 9mm wide.
At .5g, they will not be too heavy to fish with tenkara rods.
Being both heavier and smaller than the Vega spoons, the Blinde Flanker spoons should fish a bit deeper than the Vega spoons, which will be an improvement, particularly in streams.
The Blinde Flankers come with a single barbless hook.
