Hope I am not too late, but I would like to suggest my hand stamped notebooks which are £4.00 https://folksy.com/items/6942185-Gold-star-printed-notebookhttps://folksy.com/items/6942155-Red-flower-make-up-bag
Underm £5 even with the postage! A mini work of art
Just listing some glass decorations for a fiver each
Some hand painted hearts, Pack of 4
Not under £5 but good for a secret Santa gift at £6.50.
I’m having a 20% sale in my shop, so many of my purses and pencil cases are now under £5, perfect stocking fillers or secret santas! Here are just a couple
Here is a Red Fox Keyring. I photographed the Red Fox.
Sweet stocking filler
