Our spare room has been dedicated as a Mecca to all three.
These guys are also Swedish, but offer good postage speed and prices - free for All Handles & Pulls and £5 for up to 2kg for Quality Fittings.
I fitted our simple IKEA wardrobes with flat round knob (2078) from All Handles priced at £4.29 each. I fitted our Annie Sloan upcycled drawers with the Ronda globe handles, which are £2.55 each. Both have a surprising and pleasing heaviness to them.
As they were on sale, unfortunately most aren't available to buy online any more :(
