Lens-O-Rama
For the classroom or crafter (magnifying brooches and earrings?) or the home loupe manufacturer. You get half a hundred nice plastic DCX lenses, 19.5mm dia, 66mm focal length. They're packed in bulk, so there could be some very minor surface scratches.

Leonardo Rides Again
WARNING: CHOKING HAZARD-Small Parts. Not for children under 3 yrs.
Now you can re-create two of Leonardo Da Vinci's most prescient vehicles. You get everything you need to build small scale models of either his self-propelled cart or paddlewheel boat. The cart was driven by bent-wood spring tension and featured a gearing system and programmable steering. His was wood; yours is wood-like plastic, approx 6" square x 3-1/4" tall with all the right moving parts. The paddleboat was pedaled (making it a pedal-paddle boat) and your model will be approx 7-1/2" long x 2-3/4" wide x 1-1/2" tall. Both kits include a 16-page booklet with good instructions plus an overview of the maestro's life. For ages 8 and up.

Hey, Scooter!
We really like these plastic scooter wheels. They measure 3-5/16" OD x 1" wide with beveled tires so a relatively thin edge meets the road. Dual 5/16" ID bearings. You get a pair of the same color, either green or purple. The plastic material has a very slight give to it for durability. It may also have a cracked look, but that won't affect its fun or functionality quotient.
