### ⭐⭐⭐⭐⭐ Uncommon item for great price with Amazon shipping
*by M***L on October 2, 2022*

Nice to pick this stuff up through Amazon. Building a couple airplanes and source from this supplier, but sometimes you just need one small drill bit or something and don't want to pay 3x the part value for shipping.
