I've used ink spot and another vendor.. I kept using ink spot due to the easy order.. also the orice is good.. I did have a problem with some pens I ordered that would fall apart way to easy and they didn't write well these were the click pens like a bic. They weee pretty poorly made. I order about 1000 at a time and they are delivered with good speed.. I did have one problem one time it took a little longer than expected but that's not a huge problem or a resin I'll stop using them. I think they told me they were waiting for a shipment of pens so they could do mine... so the supply on their end was low but must mean they are doing well.. I have turned 2 other business owners to the ink spot.. I know review are meant to be bad most of the time so I stated the bad.. but they are a great company I won't use anyone else.. there will always be a issue when ordered something g so many times it's just like any other business... the ink spot is my go to! Also I think they should offer a special to customers or a discount on some... something of that sort.
