If you like your tech on the whimsical side, you'll probably be interested in OnePlus' latest collaboration with French designer Castelbajac. The partnership's line of "Callection" products includes a limited edition version of the OnePlus 5, complete with colorful hardware buttons and a handwriting-adorned back cover. The OnePlus 5 JCC+, which is otherwise identical to the regular OnePlus 5, is available as a 128GB variant and is on sale for the standard device price of £500 ($680). The phone will be available from pop-up events in London and Paris on September 22, and online from October 2. But if that's a bit too spendy, you can still own a piece of the Callection with a limited edition T-shirt (£30/$40) or tote bag (£25/$35), or by downloading a Castelbajac smartphone wallpaper from the Callection website.
