EC90 SL ISA SeatpostThe newly redesigned EC90 SL ISA Seatpost takes our superlight unidirectional carbon and applies our patent pending Independent Saddle Adjustment, allowing for perfect fitment with independent seat angle and fore aft movement. ISA allows you to refine your positioning without needing to undo your rail clamps for each minute tweak. Saddle angle is then locked in place so you have the confidence your saddle will stay put after you find your fit.

Pretty nice
Color: 1-Brown, Size: S
It’s kinda cheap but not too bad pretty nice overall and for the price. Good gift I noticed when I went to check and gift it that the interior had some wripples and seemed like seems (string hanging) but they actually refunded me for that. So that was really nice. It’s a good gift overall but you get what you pay for.

Nice size for valet
Color: 1-Brown, Size: S
Good size. Looks nice. Keep it handy on night stand. Holds everything from my husband's pockets & doesn't oversize the table.

Honestly Perfect
Color: 1-Black, Size: S
As a student, this Valet has made my life so much easier! I wake up around 530-6, and it's really easy to feel discombobulated so early. I keep everything I need for the day in this valet before I head out: Chapstick, gum, phone, wallet, keys, watch, even change for parking. It just makes my day so much more efficient because I can grab it and head out w/o thinking. Not to mention the material it's super sleek, affordable, and it looks great on any nightstand. It prevents me from missing anything, and its honestly one of the best investments I've made in college for just getting my day started. Thanks again Baoyun! Mad love, - Anthony
