FYI to anyone interested, these are likely a Chinese product ordered from a site like AliExpress and rebranded.
Link to AliExpress pencils that look exactly the same (with a different brand name) for roughly half the price.
Also, OP, you should note that Amazon buyers are starting to get wise to the "honest reviews" for discounts/freebies method and are outright refusing to buy products that use this method to get reviews. There's a whole website that's sole purpose is helping people decide if reviews on an Amazon product are fake/bought/poor quality. If you decide to go that route regardless of my warning, make sure that ALL reviewers follow FTC laws regarding disclosure because if you don't, well let's just say you're in a for a rude awakening when the FTC finds out. Also, please get a professional email address. It costs ~$10/year for a real domain name and it projects professionalism whereas a Gmail email account seems amateur.
And to anyone who DOES decide to review this product, PLEASE make sure you are 100% honest. If you aren't, you are doing everyone who might buy these a disservice by being dishonest just to save a few bucks. Be honest and if any company (not just the OP, he's probably a super duper awesome guy!) puts pressure on you to provide a positive review regardless of your experience, report them to the FTC.
