Budget friendly gifts for teens

[August20]

So I have to buy presents within a budget that is the equivalent of about fifteen pounds per teenager and I'm stuck! I have been given the following criteria:

• no cosmetics
• nothing in any way offensive
• nothing that requires pre-existing technology to run (e.g. no computer games)
• if it requires additional items not included (e.g. batteries) these must be given with the main present so must be included in the budget

Items should preferably be suitable for boys and girls aged 12-17. I don't know the children personally so I can't draw on knowledge of their interests or buy personalised gifts.

All I have thought of so far is sketchpads with art supplies. Anyone have any ideas?

Bullet journal kit
Himalayan salt lamp
Chess/draughts set (popular due to the Queens Gambit apparently)
Santa Banter game
Books
Bounce Off game
Jigsaw
Anime/Manga
Led strip lights

Sharpies
Stationary
Chilly style bottle
Harry Potter board game
Backpack/handbag
Lounge wear
Pyjamas
Hat, gloves and scarf
Slippers
Fluffy socks

Not art stuff, unless you know they are into art!

I would say, chocolates and sweets, silly socks, a nice cosmetics travel bag, a board game eg Codenames, a voucher for a favourite shop

Thank you all, can't believe I forgot about board games! Some great suggestions.

I''m also open to any other ideas anyone has!

Pyjamas - some of the supermarket ones are lovely and in budget.
Hot water bottle - in fact anything cuddly.
Adult colouring book and pencils.
Mug and hot chocolate stirrers.
Sports/football socks [good for boys]
Card games like Uno or Skyjo

A game like Exploding kittens
Sweets/chocs of a type that most would like.

Exploding Kittens is £13 on Amazon today, it was £19 yesterday.
