Magnets

Magnets have become very popular in healing therapy (relief of low back pain). I have no experience with that sort of magnets. I like to buy  magnets as decorations for my fridge door and as small gifts for others. These items have full or partial magnetic back adhesive.

I buy them as mementos on almost every trip. They don't take up much place in the suitcase and are quite affordable. Besides, they can last forever on the fridge door.

Needless to say, these souvenirs remind me of some lovely places, and give me much pleasure.

The only thing against them is that it might cause clutter on the fridge door; that's mainly true, Imaho, with household chore 'reminders' which we sometimes forget to take  off. 
(Well for reminders and calendar, I have a separate spot, a cork plate on the wall of my computer corner). 

Here are some of my favorite fridge magnets: 

                              babushkas (Moscow)                                  

the Kremlin (Moscow)

amber heart (Moscow)

boat (Heraklion - Crete)

ceramic coaster (Romania)

insignia (Vaduz-Lichtenstein)

Victor statue (Belgrade- Beograd)

face (indian booth - Expo fair)

landmarks (Prague - Praha)

sheep

laminated birthday card

landmarks; matchbox (Sofia)

Remarks:

'Face' and 'Heart' can be worn as pendants. Face pendant ( metal), is more suitable for men. The Belgrade item (featuring the Victor monument facing the confluence of two rivers) can be turned into a brooch.

Amber made items are very popular on Russia markets.  I own a beautiful russian amber necklace given to me as a birthday gift many years ago; time doesn't rob it of its beauty.

I've recently seen magnets in the form of the corona virus. I won't buy that one.
