I am very happy with the packaging and the quality of the Crystal and The brightness of the LED along with the Packaging it comes with that makes a great presentation for resale after has been engraved.

Super easy to use and engrave as well and very durable. Never had any issue at all!

Awesome crystal, great clarity. Designes come out great
Thanks for a great product. I will be buying more

These engrave and work very well. Sell fast and good profit margin. LED light is eye catching on the engraving. Came packed nice for each one in a nice gift box. Very satisfied. Will buy again.

THE PLUS SIDE: These little K5 Keychains are delightful and inner engrave much like their sibling the K9 Crystal.They each come in a gift box with a nice insert for shipping and they make great unexpected gifts for loved ones and an excellent way to give your clients a special something that they will probably want to order more of. The batteries that come with it seem to last about a month with occasional use. Even when they expire the crystal is still pretty cool.

THE SLIGHTLY NEGATIVE SIDE: Trying to find batteries for these has been a challenge especially since the good batteries seem to cost more than the actual keychain. The cheap batteries are lucky to last a day. XTOOL does not sell the batteries at this time but I Have a call in to the supply side and it sure would be good if they could.
