Our laptop covers can be found in 11, 13 and 15 inch widths, but all 11" laptop covers aren't the same size; the same thing goes for 13 and 15 inch covers.
In the description on all laptop covers you can find both interior and exterior measurements, the interior measurements should be a tad bit bigger than your laptop is so it fits comfortably.
This one is easier! The Pela case for iPhone 7/8 also fits iPhone 6/6s, same thing goes for the iPhone plus cases from Pela, they all work for all Plus models! As for the wood and cork cases, simply filter the products by your phone model and all cases that fit your phone will pop up, it's that easy!
If you receive your order and it still doesn't fit, contact us and we will make sure to fix the problem!
